The title compound reacted with secondary amines via the dialkylammonium-3-oxoalkyldithiocarbamate, either via isothiocyanates to 4-dialkylaminodihydro-2(1H)-pyridinethiones I (NRR1 = Et2N, piperidino, morpholino, 4-methyl-1-piperazinyl, etc.) or to dialkylammonium dithiocarbamates, depending on the amine used and the reaction conditions. Subsequently, 6-dialkylaminotetrahydro-1,3-thiazine-2-thiones II (NRR1 = morpholino, 4-methyl-1-piperazinyl) or tetrahydro-6-mercapto-1,3-thiazine-2-thione were formed. On being heated to reflux, II gave I and 4-dialkylaminodihydrothiopyranthione III. With secondary amines only dithiocarbamates were formed from tetrahydro-6-hydroxy-3,4,4,6-tetramethyl-1,3-thiazine-2-thione. The reaction of 5,6-dihydro-4,4,6-trimethyl-1,3-thiazine-2-thione with secondary amines gave N,N-dialkylthioureas or dialkylammonium thiocyanates; with dialkylformamides, 4-dialkylaminodihydropyridinethiones I were formed. 5,6-Dihyro-3,4,4,6-tetramethyl-1,3-thiazine-2-thione did not react with secondary amines or with dialkylformamides.
