Abstract

Abstract An efficient and highly stereoselective synthetic procedure is reported for the construction of symmetrical and unsymmetrical (E)-polymethoxystilbene and (E)- polyhydroxystilbene derivatives. The strategy rests on a cross-metathesis reaction catalyzed by stable, well-defined (alkylidene) ruthenium complexes, in particular the second- generation Grubbs catalyst [RuCl 2 (= CHPh)(SIMes)(PCy 3)][SIMes= 1, 3-bis (2, 4, 6- ...
