摘要

The total synthesis of luotonin A was achieved in excellent yield by using a Pd-assisted biaryl coupling reaction of N-(bromoquinolinyl) methylquinazolinone with Cy3P and KOAc. The successive treatment of luotonin A with NBS and aq. AgNO3 gave luotonin B in good yield. Although the Pd-assisted coupling reaction of N-(2-bromoindolyl) ethylquinazolinone with Cy3P and KOAc yielded rutaecarpine in poor yield, N-acetate under the same ...
