synthesis and chemical properties of designed enediynes related to dynemicin A. These modelsystems are equipped with triggering devices at C-3 of the aromatic nucleus. The design of these compounds (1 and 2) was based on the hypothesis that a C-3 phenolic group generated in situ would be capable of promoting epoxide opening and subsequent Bergman cycloaromatization according to the dynemicin A cascade
继续上一篇文章的主题,本文描述了与动力霉素 A 相关的设计烯二炔的合成和化学性质。这些模型系统在芳环的 C-3 处配备了触发装置。这些化合物(1 和 2)的设计基于这样一个假设,即原位生成的 C-3 酚基能够促进环氧化物开放和随后的 Bergman 环芳构化,根据 dynemicin A 级联
