A soln. of startg. a-chloroketimine in THF added to a soln of /-Pr2NLi in the same solvent at 0°, after 2 h acetone added dropwise, and stirring continued for 10 h with warming to room temp. - product. Y 80%. This is part of a 2-step synthesis of a,P-oxidoketones which cannot be obtained directly by the Darzens-Claisen route with diaryl ketones, P,y-ethylenecarboxylic acid amides were obtained with excess i-PrjNLi, especially in the presence of HMPA.
