Enantioselective C−C Bond Cleavage Creating Chiral Quaternary Carbon Centers
摘要:
A chiral all-carbon benzylic quaternary carbon center is created by the asymmetric intramolecular addition/ring-opening reaction of a borylsubstituted cyclobutanone, which involves enantioselective ss-carbon elimination from a symmetrical rhodium cyclobutanolate. The asymmetric reaction was successfully applied to a synthesis of sesquiterpene, (-)-alpha-herbertenol.
