2-(N-Methylanilino)-2-phenylthioacetonitrile: a useful reagent for preparation of conjugated α-amino alkenenitriles via tandem alkylation and dehydrosulphenylation
摘要:
Alkylation of the anion of 2-(N-methylanilino)-2-phenylthioacetonitrile 1 with halogenoalkanes resulted in concurrent elimination of benzenethiol to give conjugated alpha-aminoalkenenitriles of 2E-configuration. Counterattack by bromide and benzenethiolate ions was observed in the prolonged reactions of 1 with 1,4-dibromobut-2-ene and 3-bromo-1-(trimethylsilyl)prop-1-yne.

The preparation of α-cyanoenamines 4 via the condensation of casrbonyl compounds 2 with α-(N-methylanilino)-acetonitrile (1) carried out in the presence of a mixture of powdered potassium hydroxide and potassium carbonate and tetra-n-butylammonium bromide as a catalyst (solid-liquid catalytic two-phase system) is described. This reaction comprises a useful one-carbon chain lengthening of carbonyl compounds.
