R. Tillyer et al., EFFICIENT SYNTHESIS OF A-CHLORO KETONES VIA REACTION OF ORGANOMETALLIC REAGENTS WITH N-METHOXY-N-METHYLCHLOROACETAMIDE, Synlett, (3), 1996, pp. 225
A simple, high yielding synthesis of alpha-chloro ketones is described
, involving acylation of Grignard and organolithium reagents with N-me
thoxy-N-methylchloroacetamide. The efficiency of the process is furthe
r enhanced by recycling N,O-dimethylhydroxylamine.
