Rh(III)-catalyzed synthesis of benzoisothiazole spiropyrrolidinediones using sulfoximine as a directing group under a C-H activation and [4 + 1] annulation strategy with maleimides as a coupling partner is reported. The cyclization reaction was compatible with various substituted sulfoximine and maleimides. The deuterium-labeling studies were performed to investigate the mechanism of the reaction.
报道了 Rh(III)催化的使用亚砜亚胺作为导向基团的苯并异噻唑螺吡咯二酮的合成,该反应在 C-H 活化和[4 + 1]环化策略下进行,马来酰亚胺作为偶联试剂。该环化反应与各种取代的亚砜亚胺和马来酰亚胺兼容。进行了氘标记研究以探讨反应的机理。
