A total synthesis of denbinobin (1) in seven steps with an overall yield of 10% is reported. This synthesis used an FeCl3-assisted cyclization of stilbene to form a phenanthrene. The poor yields of the decarboxylation and methoxylation steps were improved upon to become essentially quantitative. This scalable methodology was carried out using ordinary laboratory reagents.
据报道,七个步骤的全合成树皮素(1)的总产率为10%。该合成使用FeCl 3辅助的苯乙烯环化形成菲。脱羧和甲氧基化步骤的产率很低,基本上就定量了。这种可扩展的方法是使用普通实验室试剂进行的。
