A practical method for the synthesis of alpha-nitroamines by Michael addition of azide to nitroalkene has been developed. This reaction proceeds in high yields under very mild conditions (phase-transfer catalysis) and is found to be general; good yields are obtained with both aryl and alkyl derivatives as well as with 1,1-disubstituted ones.
