Abstract
An efficient and general synthesis providing pyranostilbenes in moderate yields has been developed. It consists of the reaction of pinosylvin with the appropriate α,β-unsaturated aldehyde catalyzed by ethylenediamine diacetate. As an application of this methodology, biologically active natural products artocarbene and pawhuskin B were synthesized by a convergent sequence from commercially available aldehydes.
