5 S0 in acceptable overall yield from the alcohol formed on addition of lithiated thioanisole to metha~ rolein.~ The oxidation state of this alcohol was taken to the ketone level by use of the Swern procedure, and the resulting 3-methyl-l-(phenylthio)-3-buten-2-one was trimethylsilylated with TMSCl/Et3N/ZnC1: to produce stereospecifically (Z)-3-methyl-l- (phenylthio)-2-[(trimethyl-silyl) oxy]-1, 3-butadiene (la).
