An efficient synthesis of (+/-)-grandisol featuring 1,5-enyne metathesis

J Org Chem. 2010 Jan 1;75(1):226-8. doi: 10.1021/jo9020375.

Abstract

An eight-step synthesis of (+/-)-grandisol features a key sequence involving a high-yielding, microwave-assisted enyne metathesis to yield a 1-alkenylcyclobutene that is semihydrogenated to yield a silyl-protected grandisol. Metathesis catalyst screens revealed an intriguing trend whereby substrate conversion correlated strongly with the identity of the ligands on the catalyst. In addition, new reactivity of 1-alkenylcyclobutenes toward hydrogenation is described.
