Synthesis of cis bis-β-lactams via Staudinger cycloaddition reaction using C2-symmetric 1,2-diamines

An efficient stereoselective synthesis of bis-β-lactams via cycloaddition reaction (Staudinger reaction) of ketenes with bisimines derived from C2-symmetric 1, 2-diamines is described. The reaction provided diastereomeric mixture of meso and C2-symmetric cis-bis-β- lactams with higher selectivity for meso-bis-β-lactams.

Modular ligands for asymmetric synthesis: Enantioselective catalytic CuII-mediated condensation reaction of ethyl pyruvate with Danishefsky's diene

Only the correct order of addition of the components is required to prepare a variety of chiral Lewis acids. The complexes (for example, 4) formed by the condensation of chiral, nonracemic 1,2-diamines with ketones and subsequent addition of Cu(OTf)2

METALLATION OF BENZYLIDENEBENZYLAMINE

The reactions of benzylidenebenzylamine with methyllithium and lithium diethylamide were investigated by GLC.Products with different structures from condensation of the azomethine are formed: Cyclic 2,4,5-triphenyl-3-benzylimidazolidine and noncyclic dibenzylidene-1,2-diphenylethylenediamine.Investigation of the effects of the solvent, temperature, and ratio of reagents on the reaction made it possible to obtain conditions for synthetic application of the 1,3-diphenylazaallyllithium, obtained by metallation of benzylidenebenzylamine, in reactions with alkyl halides, carbon dioxide, carbonyl compounds, and phenyl isocyanate.These conditions involve a temperature between -60 and -70 deg C and an equimolar ratio between the reagents.
