A broadly-useful strategy for the introduction of a bridgehead substituent and a substituent on an adjacent carbon is described. The addition of TMSX to a bridgehead enone generates an enol silyl ether regiospecifically. Reaction of the enol silyl ether with electrophiles results in a vicinal dialkylation.
