MgBr2-promoted asymmetric addition of ArTi(OiPr)3 to ketones catalyzed by a titanium catalyst of N,N′-sulfonylated (1R,2R)-cyclohexane-1,2-diamines is reported, and results showed that the chiral N,N′-sulfonylated cyclohex

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.
