An efficient formal total synthesis of (+/-)-clavukerin A was accomplished via a gold-catalyzed cycloisomerization of a 3-methoxy-1,6-enyne 5 as the key strategy followed by Rh-catalyzed stereoselective hydrogenation of the cycloheptenone 4.
(+/-)-clavukerin A 的有效正式全合成是通过金催化的 3-甲氧基-1,6-烯炔 5 的环异构化作为关键策略完成的,然后是 Rh 催化的环庚烯酮 4 的立体选择性氢化。
