A catalytic enantioselective reaction using a C2-symmetric disulfonamide as a chiral ligand: Simmons-Smith cyclopropanation of allylic alcohols by the Et2Zn-CH2I2-disulfonamide system
摘要:
A catalytic and enantioselective Simmons-Smith Cyclopropanation of an allylic alcohol was developed by the reaction of an allylic alcohol with Et2Zn and CH2I2 in the presence of a catalytic amount of chiral disulfonamide 4.
