Gold(I)-catalyzed cycloisomerization of 1,7- and 1,8-enyne propargylic acetates afforded cyclopropyl derivatives containing seven- and eight-membered rings, respectively. This reaction was used for the synthesis of a new allocolchicinoid having a cyclopropane ring fused to the B seven-membered ring at the C6-C7 positions.
金(I)催化的1,7-和1,8-烯炔丙基乙酸酯的环异构化反应分别得到了含有七元环和八元环的环丙基衍生物。该反应被用于合成一种新的别秋水仙碱类似物,其在C6-C7位具有与B七元环稠合的环丙烷环。
