Abstract

The title synthesis involves (1) epoxidation of allylic alcohols with t-butyl hydroperoxide in the presence of vanadium catalyst followed by trimethylsilylation,(2) specific oxirane ring opening by means of diethylaluminum 2, 2, 6, 6-tetramethylpiperidide and subsequent desilylation producing 3-ene-1, 2-diols, and (3) removal of both hydroxyl groups through bromination with a mixture of phosphorus tribromide and copper (I) bromide and the ...
