A rhodium-catalyzed C-H amidation/cyclization sequence provides benzothiadiazine-1-oxides from sulfoximines and 1,4,2-dioxazol-5-ones in good yields. The reaction is characterized by a high functional group tolerance and, in contrast to most previous transformations of this type, is well-suited for alkyl--aryl-substituted sulfoximines.
铑催化的C-H酰胺化/环化反应序列能以良好产率从亚砜亚胺和1,4,2-二恶唑-5-酮制备苯并噻二嗪-1-氧化物。该反应具有高官能团耐受性,并且与大多数此类先前的转化反应不同,非常适合烷基-芳基取代的亚砜亚胺。
