A Rh-Catalyzed Air and Moisture Tolerable Aldehyde (Ketone)-Directed Fluorosulfonylvinylation of Aryl C(sp2)-H Bonds

The first Rh-catalyzed activation of ortho sp2 C-H bonds of aldehydes (ketones) for monoselective coupling with ethenesulfonyl fluoride was accomplished without covalent or transient preinstallation of imines. The 42 examples revealed that the developed method has the advantage of a wide scope and functional-group tolerability. Application of this method for complicated natural product modification was also accomplished.

Stereospecific cross-coupling reactions of aryl-substituted tetrahydrofurans, tetrahydropyrans, and lactones

The stereospecific ring-opening of O-heterocycles to provide acyclic alcohols and carboxylic acids with controlled formation of a new C-C bond is reported. These reactions provide new methods for synthesis of acyclic polyketide analogs with complex stereochemical arrays. Stereoselective synthesis of the cyclic template is utilized to control relative configuration; subsequent stereospecific nickel-catalyzed ring-opening affords the acyclic product. Aryl-substituted tetrahydrofurans and tetrahydropyrans undergo nickel-catalyzed Kumada-type coupling with a range of Grignard reagents to furnish acyclic alcohols with high diastereoselectivity. Enantioenriched lactones undergo Negishi-type cross-coupling with dimethylzinc to afford enantioenriched carboxylic acids. Application in a two-step enantioselective synthesis of an antidyslipidemia agent is demonstrated. (Chemical Equation Presented)

Structure-activity relationships of 4-(phenylethynyl)-6-phenyl-1,4- dihydropyridines as highly selective A3 adenosine receptor antagonists

4-(Phenylethynyl)-6-phenyl-1,4-dihydropyridine derivatives are selective antagonists at human A3 adenosine receptors, with K(i) values in a radioligand binding assay vs [125I]AB-MECA (N6(4-amino-3-iodobenzyl)-5′- (N-methylcarbamoyl)adenosine) in the submicromolar range. In this study, structure-activity relationships at various positions of the dihydropyridine ring (the 3- and 5-acyl substituents, the 4-aryl substituent, and 1-methyl group) were probed synthetically. Using the combined protection of the 1- ethoxymethyl and the 5-[2-(trimethylsilyl)ethyl] ester groups, a free carboxylic acid was formed at the 5-position allowing various substitutions. Selectivity of the new analogues for cloned human A3 adenosine receptors was determined vs radioligand binding at rat brain A1 and A(2A) receptors. Structure-activity analysis at adenosine receptors indicated that pyridyl, furyl, benzofuryl, and thienyl groups at the 4-position resulted in, at most, only moderate selectivity for A3 adenosine receptors. Ring substitution (e.g., 4-nitro) of the 4-phenylethynyl group did not provide enhanced selectivity, as it did for the 4-styryl-substituted dihydropyridines. At the 3-position of the dihydropyridine ring, esters were much more selective for A3 receptors than closely related thioester, amide, and ketone derivatives. A cyclic 3-keto derivative was 5-fold more potent at A3 receptors than a related open-ring analogue. At the 5-position, a homologous series of phenylalkyl esters and a series of substituted benzyl esters were prepared and tested. (Trifluoromethyl)-, nitro-, and other benzyl esters substituted with electron-withdrawing groups were specific for A3 receptors with nanomolar K(i) values and selectivity as high as 37000-fold. A functionalized congener bearing an [(aminoethyl)amino]carbonyl group was also prepared as an intermediate in the synthesis of biologically active conjugates.

A computational study of the binding of 3-(arylidene) anabaseines to two major brain nicotinic acetylcholine receptors and to the acetylcholine binding protein

Nicotinic acetylcholine receptors (nAChRs) have become targets for drug development in recent years. 3-(2,4-dimethoxybenzylidene)-anabaseine (DMXBA), which selectively stimulates the alpha7 nAChR, has been shown to alleviate some cognitive deficits associated with schizophrenia. In this paper we report an analysis of the interactions between 47 arylidene-anabaseines (including 45 benzylidene-anabaseines) and rat brain alpha7 and alpha4beta2 nicotinic acetylcholine receptors, using three different modeling techniques, namely 2D-QSAR, 3D-QSAR and molecular docking to the Aplysia californica acetylcholine binding protein (AChBP), a water soluble, homomeric nAChR surrogate receptor with a known crystal structure. Our investigation indicates the importance of: (1) the nitrogen atom of the tetrahydropyridyl (THP) ring for hydrogen bond formation; (2) pi-pi interactions between the aromatic rings of the ligands and the nAChBP binding site; (3) molecular surface recognition expressed in terms of steric complimentarity. On the basis of the 3D-QSAR results, bulky substituents at positions 2 (and due to the rotational freedom also at position 6) and 4 of the benzylidene moiety, with highly electronegative atoms projecting approximately 3-3.5 A? away from the benzylidene ring at position 4 seem optimal for enhancing binding affinity to the alpha7 nAChR.

One-pot synthesis of heteroaryl and diheteroaryl ketones through palladium-catalyzed 1,2-addition and oxidation

A synthetic method was developed for the preparation of heteroaryl and diheteroaryl ketones from aldehydes and organoboronic acids through a palladium-catalyzed 1,2-addition and oxidation that uses an aryl iodide as the oxidant. This one-pot process shows high tolerance for a broad range of heterocyclic substrates by using 1.0-3.0 mol-% of the catalyst that is formed from allylpalladium chloride dimer and a thioether-imidazolinium chloride. In addition to fine-tuning the catalytic system, the use of a sterically hindered aryl iodide that has a substituent at the ortho position, such as 2-iodotoluene, is important to obtain the desired ketones with heterocyclic moieties in good to excellent yields. The one-pot synthesis of heteroaryl and diheteroaryl ketones was achieved by a palladium-catalyzed 1,2-addition and oxidation. This catalytic process with 1.0-3.0 mol-% catalyst loading tolerates a broad range of heterocyclic substrates to give ketones with heterocyclic moieties in good to excellent yields. Copyright

Synthesis and evaluation of compounds that induce readthrough of premature termination codons

A structure-activity relationship (SAR) study was carried out to identify novel, small molecular weight compounds which induce readthrough of premature termination codons. In particular, analogs of RTC13, 1, were evaluated. In addition, hypothesizing that these compounds exhibit their activity by binding to the ribosome, we prepared the hybrid analogs 13 containing pyrimidine bases and these also showed good readthrough activity.

Highly efficient cyclization of o-iodobenzoates with aldehydes catalyzed by cobalt bidentate phosphine complexes: A novel entry to chiral phthalides

Methyl 2-iodobenzoates 1a-c undergo cyclization reactions with various aromatic aldehydes 2a-m (RC6CHO: R = H 2a, 4-CH3, 2b, 4tBu 2c, 4-OMe 2d, 3-OMe 2e, 4-C1 2f, 4-CF3 2g, 4-CN 2h, 4-Ph 2i; benzo [d][1,3]dioxole-5-carbaldehyde (2j), 1napthaldehyde (2k), benzofuran-2- carbaldehyde (21), and isonicotinaldehyde (2m)) in the presence of [CoI2(dppe)] (dppe = l,2-bis(diphenylphosphino)ethane) and Zn powder in dry THF at 75 C for 24 h to give the corresponding phthalide derivatives 3a-m and 3q-t in good to excellent yields. Under similar reaction conditions, less reactive aliphatic aldehydes, heptanal (2n), butyraldehyde (2o), and 2-phenylacetaldehyde (2p) also underwent cyclization reactions with la to provide 3n-p, respectively, in fair to good yields. The catalytic reaction can be further extended to cinnamyl aldehyde (2q) with la to give the corresponding phthalide derivative 3u. This synthetic method is compatible with a variety of functional groups on the aryl ring of 2. The high efficiency of the cobalt catalyst containing a dppe (dppe = l,2-bis(diphenylphosphino)ethane) ligand encouraged us to investigate the asymmetric version of the present catalytic reaction by employing bidentate chiral ligands. Thus, aromatic aldehydes 2a-c, 2f, and 2 g undergo cyclization with 2-iodobenzoate (la) smoothly in the presence of [CoI2{(S,S)- dipamp}] ((S,S)-dipamp = (1S,2S)-(+)-bis[2-methoxyphenyl]phenylphosphino)ethane) and zinc powder in THF at 75 C for 24 h, giving the corresponding (S)-phthalides 4a-e in 8189 % yields with 70-98 % ee. A possible mechanism for the present catalytic reaction is proposed.

Synthesis of (Z) isomers of benzoheterocyclic derivatives of combretastatin A-4: A comparative study of several methods

Several methods for the preparation of (Z) trimethoxystyrene derivatives 1 were investigated. After finding that the Wittig reaction led to unsatisfactory results, three different strategies were considered: a Suzuki coupling with a stereodefined monobromoalkene, a combination of hydrosilylation/vinylsilane hydrolysis and a palladium-catalyzed semi-hydrogenation step, using DMF/KOH as the hydrogen source. Our studies led us to prepare a series of diarylacetylene derivatives via a Sonogashira coupling reaction, and also to find out a copper-free basic cyclization leading to benzo[b]thiophenes. The final choice for the synthesis method of 1 strongly depends on the target compound but the semi-hydrogenation, which avoids the use of a toxic tin reducing agent, should be generally preferred.
