Abstract
Conjugate addition of methylamine over 2,2'-sulfonylbis(1,3-diarylprop-2-en -1-ones) in dimethylformamide gave the hitherto unknown 2,6-diaroyl-3,5-dia ryl-4-methyltetrahydro-1,4-thiazine-1,1-dioxides in very good yields. The s ame thiazines were also obtained by condensation of bis(aroylmethyl)sulfone s with aromatic aldehydes and methylamine. The structure and stereochemistr y of the compounds were deduced from elemental analysis and spectral data.
