A DIRECT SYNTHESIS OF (+/-)-ELDANOLIDE VIA THE HIGHLY REGIOSELECTIVE PRENYLATION OF 2-TRIMETHYLSILOXYFURAN

Jefford, Charles W.,Sledeski, Adam W.,Boukouvalas, John

, p. 949 - 950 (2007/10/02)

The reaction of 2-trimethylsiloxyfuran, 3,3-dimethylallyl bromide and silver trifluoroacetate produced (3,3-dimethylallyl)-4-but-2-en-4-olide with high double regiodifferentiation.The latter compound on treatment with lithium dimethylcuprate gave (+/-)-eldanolide in high yield.
