Very simple, chiral, non-racemic diselenides were prepared and their corresponding seleniumelectrophiles were used for the stereoselective functionalization of alkenes. The influence of different alkenes on the outcome of the selenenylation reaction was investigated.
A new methodology for the asymmetric synthesis of beta-hydroxy acid was developed. Dirhodium(II)-catalyzed C-H insertion of alpha-alkoxydiazoketone (3), which was prepared from primary alkyl halide (1) and readily available chiral alpha-hydroxy acid (2), gave stereoselectively 2,5-cis-disubstituted 3(2H)-furanone (4). The Baeyer-Villiger reaction of 4 followed by treatment with an acid afforded chiral

A general procedure for the asymmetric synthesis of highly substituted 1,2-amino alcohols in high yield and diastereoselectivity is described that uses organometallic additions of a wide range of nucleophiles to tert-butylsulfinimines as the key step. The addition of organolithium reagents to these imines follows a modified Davis model. The diastereoselectivity for this reaction depends significantly
