Studies directed toward total synthesis of rhodocomatulins: A regioselective synthesis of brominated hydroxyanthraquinones by anionic annulations

In this work, brominated hydroxyanthraquinones, which are the core structural motif of naturally occurring bromorhodocomatulins, were successfully synthesized using Hauser annulation reaction as the key step. When brominated Michael acceptors (brominated p-quinone monoketals) and cyanophthalides or bromocyanophthalides (Hauser donors) were reacted under the annulation conditions, brominated anthraquinones were obtained with 81?87% yields for four examples. On acidic quenching, products were obtained as solid which were separated by filtration and purified by recrystallization in acetone. No chromatography was required.

Visible-light-mediated efficient conversion of aldoximes and primary amides into nitriles

A photosensitization-based approach for a convenient and efficient conversion of aldoximes and primary amides into nitriles is reported. The protocol involves eosin Y catalysed, visible-light-mediated in situ formation of the Vilsmeier-Haack reagent from CBr4 and a catalytic amount of DMF, which brings about the desired transformation to afford nitriles at r.t.

Novel orally active antimalarial thiazoles

An aminomethylthiazole pyrazole carboxamide lead 3 with good in vitro antiplasmodial activity [IC50: 0.08 muM (K1, chloroquine and multidrug resistant strain) and 0.07 muM (NF54, chloroquine sensitive strain)] and microsomal metabolic stability was identified from whole cell screening of a SoftFocus kinase library. Compound 3 also exhibited in vivo activity in the P. berghei mouse model at 4 ¡Á 50 mg/kg administration via the oral route, showing 99.5% activity and 9 days survival and showed low in vitro cytotoxicity. Pharmacokinetic studies in rats revealed good oral bioavailability (51% at 22 mg/kg) with a moderate rate of absorption, reasonable half-life (t1/2 3 h), and high volume of distribution with moderately high plasma and blood clearance after IV administration. Toward toxicity profiling, 3 exhibited moderate potential to inhibit CYP1A2 (IC50 = 1.5 muM) and 2D6 (IC50 = 0.4 muM) as well as having a potential hERG liability (IC50 = 3.7 muM).

A Unified Strategy for the Synthesis of beta-Carbolines, gamma-Carbolines, and Other Fused Azaheteroaromatics under Mild, Metal-Free Conditions

An efficient, unified approach for the synthesis of beta-carbolines, gamma-carbolines, and other fused azaheteroaromatics has been realized under metal-free conditions, from propargylic amines and (hetero)aromatic aldehydes. This unified strategy provides beta- and gamma-carbolines as well as a range of fused azaheteroaromatics with a broad substrate scope and excellent functional group compatibility. The formal synthesis of oxopropalines D and G has been achieved on gram scale (3a), in a one-pot reaction from commercially available materials (previous shortest reported route to 3a was 5 steps). NMR studies of the conversion of imine intermediate 3aa to beta-carboline 3a were conducted and revealed that the reaction proceeded through an allene intermediate.

Copper-Catalyzed Asymmetric Arylation of N-Heteroaryl Aldimines: Elementary Step of a 1,4-Insertion

Copper complexes of monodentate phosphoramidites efficiently promote asymmetric arylation of N-azaaryl aldimines with arylboroxines.

Carbonation-induced corrosion: Investigation of the corrosion onset

There are different views in the literature on the relationship between the location of the carbonation front and the onset of reinforcement corrosion. Theoretically, corrosion starts when the carbonation front reaches the reinforcement, but some authors have observed an apparent earlier start of corrosion. In the present study, mortar samples with and without reinforcement were exposed for up to 22 weeks to 20 C, 60% RH and 1.5% CO2. The state of the reinforcement was monitored by potential measurements. The carbonation of the bulk and the mortar-steel interface was detected by spraying a pH indicator on a freshly split or cut surface. Good agreement was found between low potential values (compared to reinforcement in the passive state) and the carbonation of the mortar-steel interface. A difference in the spatial variation of the carbonation depth was observed between plain and reinforced samples. The differences found in the literature between the location of the carbonation front and the corrosion onset can probably be explained by the spatial variation of the carbonation depth in the vicinity of the reinforcement.

The Discovery of Potent Nonpeptide Angiotensin II Receptor Antagonists: A New Class of Potent Antihypertensives

A new class of potent antihypertensives has been discovered that exert their effect through blockade of the angiotensin II (AII) receptor.Most AII antagonists reported so far are peptide mimics of the endogenous vasoconstrictor octapeptide angiotensin II.The compounds of this paper are nonpeptides and therefore constitute a new class of potent AII receptor antagonists.Based on the overlap of a conformation of AII with literature lead 3, a hypothesis was developed suggesting the need for an additional acidic functionality to increase the lead’s potency.The substitution of an additional carboxylic acid resulted in a 10-fold increase in binding affinity observed for diacid 4.The binding affinities for subsequent compounds were eventually increased 1000-fold over that of the literature leads through a systematic SAR study.Thus the AII receptor binding affinity of 15 muM for literature lead 1, for example, was increased to 0.018 and 0.012 muM for compounds 33 and 53.A structure-affinity relationship has been found requiring the presence of four key elements for good activity: (1) an additional phenyl ring at the N-benzyl para position of the benzylimidazole nucleus, (2) an acidic functionality at the ortho position of the terminal aromatic ring, (3) a lipophilic side chain at the imidazole 2-position of three to five carbon atoms in length, and (4) a group at the imidazole 5-position capable of hydrogen bonding.The synthesis as well as the pharmacological activity of the compounds in this new series of AII receptor antagonists are presented.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 52079-23-9!, 14963-96-3

Ru-Catalyzed Selective C-H Bond Hydroxylation of Cyclic Imides

We report on cyclic imides as weak directing groups for selective monohydroxylation reactions using ruthenium catalysis. Whereas acyclic amides are known to promote the hydroxylation of the C(sp2)-H bond enabling five-membered ring ruthenacycle intermediates, the cyclic imides studied herein enabled the hydroxylation of the C(sp2)-H bond via larger six-membered ruthenacycle intermediates. Furthermore, monohydroxylated products were exclusively obtained (even in the presence of overstoichiometric amounts of reagents), which was rationalized by the difficulty to accommodate coplanar intermediates once the first hydroxyl group was introduced into the substrate. The same reactivity was observed in the presence of palladium catalysts.
