Abstract
The reaction of an ester with N,O-dimethylhydroxylamine and a suitable organomagnesium reagent or lithium amide base provides a general meth od for the preparation of N-methoxy-N-methylamides. Application in the direct conversion of a highly hindered ester to a ketone, the azaster oid 5 alpha-reductase inhibitor MK-0434, is described.
