摘要:An Enantio-And Diastereoselective Sakurai-Hosomi Reaction,Catalyzed By Chiral Scandium Pyridyl-Bis(Oxazoline) (Pybox) Complexes,Has Been Developed. Both Alkyl-And Aryl-Substituted Allylsilanes Are Effective Coupling Partners With N-Phenylglyoxamide. Applications Of This Reaction To The Asymmetric Syntheses Of N-Boc D-Alloisoleucine And D-Isoleucine Are Described.
