Synthesis of novel 3,5-disubstituted-4-isothiazolecarbonitriles
Mishra, Manisha,Dutta Chowdhury,Mahalanabis, Kumar K.
, p. 2681 - 2689 (2004)
α-Cyano-β-enaminones, obtained by regioselective acylation of β-enaminonitriles, were smoothly converted to thiones which on oxidative cyclization afforded 3,5-disubstituted-4-isothiazolecarbonitriles in good to excellent yields.
