Abstract

Efficient and general synthetic protocols were developed for the total synthesis of ailanthoidol, egonol, and some related analogues. The key transformations describe here involve a two-step construction of the benzofuran and a Sonogashira coupling, and proved to be convenient and effective, starting from readily available reagents.
