the products were identified, by spectral studies as well as by chemical transformations, as the corresponding Diels-Alder adducts of benzoylsulfene as a dienophile to the α,β-unsaturated anils, 2-substituted 5H, 6H-6-benzoyl-5-phenyl-1,2-thiazine 1,1-dioxides, in which the phenyl and benzoyl groups are quasi-equatorial and quasi-axial respectively. The cycloadducts underwent inversion, on treatment
研究了苯甲酰甲磺酰氯与肉桂基胺在三乙胺存在下的反应;通过光谱研究和化学转化,这些产物被鉴定为苯甲酰亚砜的相应 Diels-Alder 加合物作为 α,β-不饱和苯胺、2-取代 5H、6H-6-苯甲酰-5-苯基的亲二烯体-1,2-噻嗪 1,1-二氧化物,其中苯基和苯甲酰基分别为准赤道和准轴。环加合物在甲醇中用甲醇钠或在氯仿中用硅胶处理后发生转化,转化为相应的差向异构体,其中苯基和苯甲酰基都是准赤道的。
