摘要:
General solution: An efficient rhodium-catalyzed dual CiH bond activation and cyclization of N-methoxybenzamides 1 with aryl boronic acids 2 (see scheme; Cp=Me5C5) provides a straightforward and general approach to the phenanthridinone structure, which occurs widely in natural products and drugs. Highly regioselective CiC and CiN bond formation under mild conditions afforded a wide range of substituted phenanthridinones 3. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
