摘要：
A chiral disulfonamide-alkylaluminum complex prepared from (1R,2R)-N,N'-bis(benzenesulfonyl)-1,2-cyclohexanediamine and trialkylaluminum or i-Bu2AlH has been found to catalyze a Simmons-Smith cyclopropanation of allylic alcohols with Et2Zn and CH2I2 to afford the corresponding cyclopropanes in excellent yields with high enantiomeric excesses.
