Studies of the reaction of substituted 1,2-dithiole-3-thiones and -3-ones with sodium cyanide in acetonitrile
Résumé
The reactions of substituted 1,2‐dithiole‐3‐thiones and ‐3‐ones with sodium cyanide, in acetonitrile, afford convenient routes to indolizine, pyrrolo[1,2‐a]pyrazine and 4H‐1,3‐thiazin‐4‐one species.
