Some ring closure reactions with cyanothioformamides: New route for the synthesis of (imidazolidine, oxazolidine & pyrroline)-iminothiones, benzothiazoloquinazolinones and imidazoquinoxalines

Article abstract of DOI:10.1080/10426500008043677

Cyanothioformamides were reacted with isocyanates, isothiocyanates, aldehydes, acetylenedicarboxylic acid and anthranilic acids to produce imidazolidines, oxazolidines pyrroline, quinazolinones and benzothiazoloquinazolinones, respectively. Interaction of imidazolidineimino(thiones and dithiones) with o-phenylenediamines gave rise to imidazoquinoxalines and imidazoquinoxalinethiones, respectively.
