Synthesis of some novel α-cyanoketene-n, s-acetals derived from secondary aliphatic amines and their use in pyrazole synthesis

Al-Adiwish, Wedad M.,Tahir,Yaacob

, p. 3203 - 3216 (2013)

New α-cyanoketene-N,S-acetals 2(a-g) and β-dialkylamine-α- cyanoacrylates 3(g-i) were synthesized in good to excellent yields by the reaction of ethyl 2-cyano-3, 3-bis(methylthio)acrylate 1 with secondary aliphatic amines (i.e., N-methylalkyl- and N-ethyl
