Abstract
The first total synthesis 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.
Key words
benzofuran - neolignan - McMurry reaction - Suzuki coupling
