Lm. Makarenkova et al., The chemistry of N,N-bis(trialkylsilyloxy)enamines 2. Alkylation of primary amines with N,N-bis(trimethylsilyloxy)enamines, RUSS CHEM B, 49(7), 2000, pp. 1261-1269
The reactions of primary amines with N,N-bis(trimethylsilyloxy)enamines can
give products of both mono- and bis-alpha-oximinoalkylation of primary ami
nes. The steric restrictions in both reactants substantially retard bis-alp
ha-oximinoalkylation. A general method for the synthesis of alpha-amino-sub
stituted oximes from primary amines and bis-silyl derivatives of aliphatic
nitro compounds was developed.
