Rh(III)-catalyzed regioselective C−H activation/[3+2] cyclization of KHAs with iodonium ylides accessing pyrimido[1,2-a]indole derivatives

Herein, we present a protocol for the regioselective construction of two kinds of functionalized pyrrole derivatives, i.e., pyrimido[1,2-a]indole derivatives (PIIDOs) 3−4 from HKAs with iodonium ylides promoted by AgSbF6 (Lewis...
