A pentacyclic compound was synthesized as an important intermediate of antitumor antibiotic dynemicins. The key step was the intramolecular Heck reaction using catalytic Pd reagent. During the course of the synthetic studies, an unusual spiro ring compound was found to be produced via intramolecular conjugate addition.
合成了五环化合物,作为抗肿瘤抗生素迪尼米星的重要中间体。关键步骤是使用催化钯试剂进行的分子内Heck反应。在合成研究过程中,发现一种异常的螺环化合物是通过分子内共轭物加成产生的。
