Efficient and general synthetic protocols were developed for the totalsynthesis of ailanthoidol, egonol, and some relatedanalogues. 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. benzofurans - cross-coupling - McMurry reaction - Sonogashira coupling

of four naturally occurring benzofuran neolignans and two analogues was achieved in four steps in 44-51% overall yield. Key steps involved a two-step construction of benzofuran nucleus and a Suzuki coupling. This synthesis has been proven straightforward and efficient, and more related analogues can be prepared for structure-activity relationship explorations. benzofuran - neolignan - McMurry reaction
