  An efficient method for the optical resolution of 3-hydroxy-2-substituted-4-alkynoates: a highly stereoselective total synthesis of (+)-bengamide E1

  摘要：

  A novel. procedure for the optical resolution of 3-hydroxy-2-substituted-4-alkynoates and its application to the stereoselective total synthesis of (+)-bengamide E are described. 3-Hydroxy-2-substituted-4-alkynoates, derived from the aldol reaction of cobalt-complexed propynals with ketene O-silyl O,S-acetals, were easily resolved by the formation of a chiral carbamate followed by cobalt complexation. Chiral 2-(benzyloxy)-3-hydroxy-4-alkynoate derivatives thus obtained were used as starting materials for a highly stereoselective total synthesis of (+)-bengamide E.
