Abstract

An efficient synthesis of the natural product (–)-gummiferol is achieved according to a novel asymmetric methodology of epoxide formation based on a new class of chiral sulfonium salts. This new methodology allows the rapid and efficient construction of the diepoxide system contained within the natural product.
