A synthesis of tetrahydropyrimidine-dithiones and octahydroquinazoline-dithiones has been realized by direct action, in basic media, of alkyl or aryl isothiocyanates on ketones possessing at least an hydrogen atom in an α-position.The clarification of the complex mechanism of this reaction has been attempted.It is possible to reach corresponding diones by desulphurization of the dithiones.
