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. heterocycles - alkenes - phenols - artocarbene - pawhuskin B
