摘要
2-Imino-2'-methyl biaryls, conveniently available by Suzuki cross coupling protocol, undergo lithium diethyl amide-mediated metalation - cyclization to give 9-aminophenanthrenes (Table 1). The application of this new general methodology to the first synthesis of the alkaloid piperolactam C (9) is described. (C) 1998 Elsevier Science Ltd. All rights reserved.
