Mono-N-alkylation of α-Aminoacetonitriles. A Novel Route to Unsymmetrical Secondary Amines

Katritzky, Alan R.,Latif, Muhammad,Urogdi, Laszlo

, p. 667 - 672 (2007/10/02)

Mannich-type condensation products of an aldehyde with an α-aminoacetonitrile and benzotriazole are treated with sodium borohydride or with a Grignard reagent to give unsymmetrical N,N-dialkylaminoacetonitriles, which, on decyanomethylation provide unsymmetrical secondary amines.
