Enantioselective epoxidation of tertiary allylic alcohols by chiral dihydroperoxides
摘要:
gem-Dihydroperoxides were successfully used for the enantioselective epoxidation of tertiary and primary allylic alcohols. Epoxides derived from tertiary alcohols were obtained in yields up to 71% with ee's up to 52%. (c) 2013 Elsevier Ltd. All rights reserved.
