4- -1 -silyloxy-1 -alkene ester

Acyloin condensations of esters conducted with TMS-Cl and sodium in toluene give 1,2-bis(trimethyl-silyloxy)alkenes. In general, the silylacyloin reaction provides higher yields than the conventional acyloin reaction and is particularly useful for the preparation of cyclic enol silyl ethers. " The synthesis of compound (47) serves as an illustration. [Pg.602]
