1,4-Addition of the enolate generated from methyl 6-deoxy-2,3-di-O-(t- butyldimethylsilyl)-4-O-propionyl-α-D-glucopyranoside to methyl crotonate provided a single anti-adduct with exceptionally high stereoselectivity. From this adduct, (-)-lasiol, an acyclic monoterpene alcohol isolated from the males of Lasius meridionalis ants, was synthesized concisely.
