Synthesis of Novel 3,5‐Disubstituted‐4‐isothiazolecarbonitriles
摘要:
alpha-Cyano-beta-enaminones, obtained by regioselective acylation of beta-enaminonitriles, were smoothly converted to thiones which on oxidative cyclization afforded 3,5-disubstituted-4-isothiazolecarbonitriles in good to excellent yields.
