Abstract Conjugate addition of methy lamine over 2,2′-sulfonylbis(1.3-diarylprop-2-en-1-ones) in dimethylformamide gave the hitherto unknown 2.6-diaroyl-3,5-diaryl-4-methyltetrahydro- 1.4-thiazine-1,1-dioxides in very good yields. The same thiazines were also obtained by condensation of bis(aroylmethyl)sulfones with aromatic aldehydes and methylamine. The structure and stereochemistry of the compounds
摘要 在二甲基甲酰胺中的 2,2'-磺酰基双 (1.3-diarylprop-2-en-ones) 上与
甲胺共轭加成得到了迄今为止未知的 2.6-diaroyl-3,5-diaryl-4-methyltetrahydro-1.4-thiazine- 1,1-二氧化物的产率非常好。通过双(芳酰基甲基)砜与芳香醛和
