  摘要：

  While thermolysis of the macrobicyclic triene lactone 12 did not produce the expected bicyclic transannular Diels-Alder (BTADA) product 13. heating the corresponding ether 18 to 110 degrees C for 4 h afforded a quantitative yield ol the desired cycloadduct 19. which could be easily reduced to the perhydrophenanthrene. an ABC ring analogue of lusidic acid 1 Theoretical calculations with hybrid density functional theory (B3LYP/6-31G(d)) help rationalize why the lactone does not cyclize whereas the ether does
