Assembly of Tetrahydropyran Derivatives from Aldehydes, Allylboronates, and Syngas by Asymmetric Relay Catalytic Cascade Reaction

An efficient synthesis of highly enantio-enriched tetrahydropyrans from readily available aldehydes, allylboronates, and syngas has been established by multiply relay catalysis of rhodium and chiral phosphoric acid. The cascade reaction integrates the asymmetric allylboration of aldehydes and alkene hydroformylation, providing a structurally diverse range of products with different workup procedures. The concise synthesis of key chiral building blocks to access herboxidiene and leucascandrolide A demonstrates the high synthetic utility of this method. The cascade reaction employing alkenes to replace aldehydes was also successful.

Probing the mechanism of allylic substitution of morita-baylis- Hillman acetates (MBHAS) by using the silyl phosphonite paradigm: Scope and applications of a versatile transformation

A P-C bond-forming reaction between silyl phosphonites and Morita-Baylis-Hillman acetates (MBHAs) is explored as a general alternative towards medicinally relevant I2;-carboxyphosphinic structural motifs. Conversion rates of diversely substituted MBHAs to phosphinic acids 9 or 14that were recorded by using 31P NMR spectroscopy revealed unexpected reactivity differences between ester and nitrile derivatives. These kinetic profiles and DFT calculations support a mechanistic scenario in which observed differences can be explained from the “lateness” of transition states. In addition, we provide experimental evidence suggesting that enolates due to initial P-Michael addition are not formed. Based on the proposed mechanistic scenario in conjunction with DFT calculations, an interpretation of the E/Z stereoselectivity differences between ester and nitriles is proposed. Synthetic opportunities stemming from this transformation are presented, which deal with the preparation of several synthetically capricious phosphinic building blocks, whose access through the classical P-Michael synthetic route is not straightforward.

Synthesis and Biological Activity of Novel (E)-N?-(Substituted)-3,4,5-trimethoxybenzohydrazide Analogs

The hydrazide-hydrazone analogs 4a-4l is described via the condensation of 3,4,5-trimethoxybenzohydrazide 3 with various aromatic and hetero aromatic aldehydes a-l. Various spectroscopic techniques viz., (1H NMR, 13C NMR, IR and MS) were utilized to determine the structures of synthesized compounds. These compounds were evaluated for antibacterial, antifungal screening against S.aureus, S.pyogenes, E.coli, P.aeruginosa, Aspergillus niger and Candida albicans (Fungal strains). The results revealed that most of the hydrazone derivatives exhibited significant antibacterial activity. Furthermore, the synthesized hydrazone derivatives were found to exhibit significant antidiabetic activity when compared to insulin.

Palladium-catalyzed decarboxylative benzylation of diphenylglycinate lmines

(Figure presented) General reaction conditions for the Pd-catalyzed decarboxylative benzylation of benzyl diphenylglycinate lmines are described. The overall procedure requires a simple catalyst/ligand combination to form a new Csp3-Csp3 bond. Microwave Irradiation greatly accelerated the transformation. Moreover, various heteroaromatlc moieties are tolerated in both the imine and ester components.

Telescoped enolate arylation/HWE procedure for the preparation of 3-alkenyl-oxindoles: The first synthesis of soulieotine

A. telescoped sequence involving palladium-catalysed intramolecular enolate arylation followed by an in situ HWE olefination has been developed to provide rapid access to 3-alkenyl-oxindoles. This “one-pot” process, which is greatly accelerated by microwave irradiation, proceeds with low loadings of palladium (II) acetate (0.2-1.0 mol-%), and has been used to prepare a range of adducts derived from aromatic, heteroaromatic and aliphatic aldehydes as well as formaldehyde. In addition, further elaboration of the formaldehyde adducts are described. The applicability of the process has been established by carrying out the first synthesis of Soulieotine, a constituent of a traditional Chinese medicine. Wiley-VCH Verlag GmbH & Co.

Synthesis and Insecticidal Activity of Spinosyns with C9- O -Benzyl Bioisosteres in Place of the 2?,3?,4?-Tri- O -methyl Rhamnose

The spinosyns are fermentation-derived natural products active against a wide range of insect pests. They are structurally complex, consisting of two sugars (forosamine and rhamnose) coupled to a macrocyclic tetracycle. Removal of the rhamnose sugar results in a >100-fold reduction in insecticidal activity. C9-O-benzyl analogues of spinosyn D were synthesized to determine if the 2?,3?,4?-tri-O-methyl rhamnose moiety could be replaced with a simpler, synthetic bioisostere. Insecticidal activity was evaluated against larvae of Spodoptera exigua (beet armyworm) and Helicoverpa zea (corn earworm). Whereas most analogues were far less active than spinosyn D, a few of the C9-O-benzyl analogues, such as 4-CN, 4-Cl, 2-isopropyl, and 3,5-diOMe, were within 3-15 times the activity of spinosyn D for larvae of S. exigua and H. zea. Thus, although not yet quite as effective, synthetic bioisosteres can substitute for the naturally occurring 2?,3?,4?-tri-O-methyl rhamnose moiety.

Fe(III)-Catalyzed Aerobic Intramolecular N-N Coupling of Aliphatic Azides with Amines

An Fe(III)-catalyzed intramolecular N-N coupling of aliphatic azidoamines that forms diverse five- and six-membered semisaturated diazoheterocycles using air as an oxidant is reported, providing an alternative to hydrazine-based methods. Mechanistic studies suggest that a N-radical induced intramolecular homolytic substitution (SH2) is involved in ring closure. The power of this N-N bond-forming method is also demonstrated by using it as the final step in a total synthesis of (-)-newbouldine.
