摘要：

The synthesis of the model systems 10 and 22 of dynemicin A (2) containing the nitrogen, enediyne, and epoxide functionalities has been achieved. These models are shown to undergo acid-induced triggering to give the corresponding Bergman-cyclized products in the presence of suitable H atom donors. Removal of the N protecting group from 22 gave the unstable free amine 30, which was shown to cause double-stranded-DNA cleavage, presumably in a manner similar to that of dynemicin A (2) itself. Some interesting chemistry related to dicobalt complexes of the enediynes is also presented.
