The large effects of minimal structural variations are demonstrated by enediynes 1 . At 50 °C the cis isomer cyclizes much faster ( t 1/2 = 4 h) than the trans isomer ( t 1/2 = 22 h). The carbonate derivative of trans ‐ l is stable even for several hours at 100 °C. The exploration of the chemistry of cyclic enediynes is prompted by their DNA‐cleaving properties.
