Synthetic studies on hemicalide: development of a convergent approach toward the C1-C25 fragment

Abstract

Synthetic studies on hemicalide, a recently isolated marine natural product displaying highly potent antiproliferative activity and a unique mode of action, have highlighted a reliable Horner-Wadsworth-Emmons olefination to create the C6-C7 alkene and a remarkable efficient Suzuki-Miyaura coupling to form the C15-C16 bond, resulting in the development of a convergent approach toward the C1-C25 fragment.
