文摘
An electron-deficient CpE-rhodium(III) complex catalyzes the tandem [2+2+2] annulation–lactamization of acetanilides with two alkynoates via cleavage of two adjacent C−H bonds to give densely substituted benzo[cd]indolones. Surprisingly, the reactions of meta-methoxy-substituted acetanilides with two alkynoates also provided benzo[cd]indolones via unprecedented cleavage of adjacent C−H and C−O bonds. In contrast, 3,5-dimethoxyacetanilides reacted with two alkynoates to give dearomatized spiro compounds.
