  Synthetic studies on the compounds related to neocarzinostatin chromophore. 1. Synthesis of the acyclic (E)- and (Z)-dienediyne systems

  摘要：

  The stereo-defined (E)- and (Z)-dienediyne systems related to neocarzinostatin chromophore (1) could be prepared by the coupling reaction of (E)- and (Z)-enol triflates with optically active acetylynes hearing the correct absolute stereochemistries as found in 1. Comparison of cytotoxic level of the (E)- and (Z)-dienediyne diols (32 and 33) revealed that the stereochemistry of exo-trisubstituted double bond might have a posibility to control the cytotoxicity of the acyclic analogues related to I.
