Cyclic silyl enol ethers were successfully cleaved by EtOK to generate the corresponding enolates. Reactions with EtOK; were faster and the corresponding enolates could be trapped by electrophiles and oxidants to give the kinetic products exclusively. (C) 2001 Elsevier Science Ltd.

selenium dioxide-mediated allylic oxidation of 80 and a highly stereoselective 1,4-addition of alpha-alkoxy vinylcuprates 68 to steroid 17(20)-en-16-one 12E to introduce the steroid side chain. This total synthesis demonstrated once again the versatile syntheticapplications of alpha-halo vinyl ether chemistry developed in our laboratories.
