A new disulfonamide prepared from α-amino acid in five steps catalyzed cyclopropanation of allylic alcohols with Et2Zn and CH2I2 to afford the corresponding cyclopropylmethanols in moderate to good enantioselectivites. In particular, the reaction of cinnamyl alcohol in the presence of a chiral disulfonamide 1k afforded an excellent enantioselectivity (85% ee).

A series of (β-N-sulfonylaminoalkyl)phosphine ligands has been developed and employed for asymmetric palladium-catalyzed hydrosilylation and Heck-type hydroarylation, affording up to 72% ee and 90% yield.
