The role played by stereochemistry in the C2-substituent (left part) on the S-DABO scaffold for anti-HIV-1 activity has been investigated for the first time. A series of S-DABO analogues, where the double bond in the C2-substituent is replaced by an enant

The catalytic, enantioselective cyclopropanation of cinnamyl alcohol has been accomplished with bis (iodomethyl)zinc in the presence of chiral bis(sulfonamides) derived from cyclohexanediamine. An extensive survey of diamine and sulfonamide structure has revealed a marked sensitivity to the spatial relationship of the amine groups, but only a modest dependence on the sulfonamide residue.

Excellent enantioselective alkylation of aldehydes with dialkylzinc has been developed.This methodology is based on the concept of modifying the Lewis acid with a C2-symmetric, electron-withdrawing disulfonamide.The chiral Lewis acid catalysts used in the present study are the titanium complexes, prepared in-situ from disulfonamide and Ti(O-i-Pr)4.Key Words: Chiral disulfonamide; chiral titanium complex; enantioselective alkylation; dialkyl zinc; catalytic reaction
