One-Pot Synthesis of 3,3-Dimethylpyrrolidine-2-carbonitriles from 4-Chloro-2,2-dimethylbutanal in Water
摘要:
Treatment of 4-chloro-2,2-dimethylbutanal, prepared in high yield by means of a three-step procedure starting from ethyl isobutyrate, with successively sodium bisulphite, a primary amine and potassium cyanide in water afforded novel 1-alkyl- and 1-aryl-3,3-dimethylpyrrolidin-2-carbonitriles in a convenient and environmentally benign way.
