have developed a strategy of Rh(III)-catalyzed C—H activation of N-nitrosoanilines and iodonium ylides to construct novel tetralydrocarbzol-4-one scaffolds, which provided valuable templates for sequential C—H functionalization such as alkylation, alkenylation, amidation and (hetero)arylation at C5-position of tetralydrocarbzol-4-one with different coupling partners. Gram-scale synthesis and further transformations
在此,我们开发了一种Rh(III)催化N-亚硝基苯胺和碘鎓叶立德的C-H活化策略,构建新型四氢咔唑-4-酮支架,为连续的C-H功能化(例如烷基化、烯基化)提供了有价值的模板四氢咔唑-4-酮的C 5位上的酰胺化和(杂)芳基化与不同的偶联配偶体。四氢咔唑-4-酮衍生物的克级合成和进一步转化为昂丹司琼及其类似物证明了该方案的实用性,使得生物活性分子的简洁和多样化的构建成为可能。
