Synthesis and X-ray analysis of butyl and glycosyl (2-arylamino-4,4-dimethyl-6-oxocyclohex-1-ene)carbodithioates and their possible cyclization to 2-thioxo-6,7-dihydro-1H-benzo[d][1,3]thiazin-5(2H)-one derivatives

Variety of butyl [2-arylamino-4,4-dimethyl-6-oxo-cyclohex-1-ene]carbodithioates (3a–c), 2-thioxo-6,7-dihydro-1H-benzo[d][1,3]thiazin-5(2H)-one derivatives (5a–c), and the glucosyl carbodithioates 6a–c as well as galactosyl carbodithioates 7a–c have been synthesized from the reaction of enaminone derivatives 1a–c with carbon disulfide followed by the alkylation with n-butyl bromide and α-d-glycosyl bromides, respectively. The amount of carbon disulfide plays a great role in the mode of reaction. The structures of the synthesized compounds were elucidated by spectral data and X-ray crystallography.
