Abstract

Abstract: A five-step synthesis of (*)-albene from 2, 3-dicarbomethoxynorbornene utilizes the palladium-catalyzed cycloaddition of 2-((trimethylsilyl) methyl)-3-acetoxy-1-propene as the key reaction. Deoxygenation to the hydrocarbon takes advantage of the treatment of phosphoramidates with lithium. This procedure nicely resolves the problems of conversion of a ketone to an olefin and a neopentyl ester to a methyl group, which permits both types ...
