Ketones, amides, and thioesters form enolsilanes and add to N-phenylnitrones in one pot in the presence of trimethylsilyl trifluoromethanesulfonate and trialkylamine. The reaction is general to a range of silyl trifluoromethanesulfonates and N-phenylnitrones. The β-(silyloxy)amino carbonyl products are stable to chromatography and can be isolated in 63–99 % yield.
