Enaminones 2, easily prepared from the corresponding sodium salts of beta -ketoaldehydes 1 and hydrochlorides of primary amines, react with carbon disulfide/sodium hydride to give dithiocarbamates 3 after alkylation. In a similar way thiocarbamoylation yields isothioureas 4. The C-13 NMR parameters of 2, 3 and 4 show significant low- and high-field shifts of the C-1 and C-2 signals, respectively.
