The aldol reaction using aldehyde-derived silyl enolates as nucleophiles with aromatic aldehydes chemoselectively proceeded in the presence of silyl triflate and 2,2′-bipyridyl to produce β-siloxy aldehydes, while the aliphatic aldehydes were completely recovered. The unprecedented chemoselectivities depend on the reactivities of the pyridinium-type intermediates derived from the aromatic and aliphatic aldehydes.

Oxidation of E- and Z-vinyl lithiums with silyl peroxides 5 affords silyl enol ethers 3 in good to excellent yield with retention of configuration.This methodology represents a useful new procedure for the stereo and regioselective synthesis of ketone eno
