Abstract
The reaction of azaallylic anions with ethyl N-[4-nitrobenzenesulfonyl )oxy]carbamate in the presence of a base gives a mixture of an alpha-a mino ketone derivative with a slight preference for the (S) enantiomer and of an alpha-hydrazino ketone derivative as by-product; the same a zaenolates react with bis(tert-butoxycarbonyl)diazene giving the analo gous alpha-hydrazino ketone derivative, with a slight preference for t he (R) enantiomer.
