Abstract

A variety of racemic epoxides mainly derived from terminal olefins, such as aliphatic epoxides, multifunctionalized epoxides and amine-substituted epoxides, have been successfully resolved into the enantiomerically pure epoxides and diols using ­Jacobsen’s hydrolytic kinetic resolution (HKR) method. The chiral epoxides thus prepared were further elaborated by synthetic manipulation to provide a variety of compounds of biological interest. A general synthetic strategy for the construction of syn/anti-1,3-polyol systems using iterative HKR has been developed, which was subsequently utilized in the synthesis of natural products with a broad range of biological activity. The protocol for the 1,3-polyols was also further extended to the synthesis of 1,3-amino alcohols.
