The stereoselective total syntheses of (±)-α-vetispirene, (±)-hinesol, and (±)-β-vetivone were accomplished based on a Claisen rearrangement in an alkenyl bicyclic dihydropyran system. The most striking feature of this approach is that the Claisen rearrangement of bicyclic dihydropyran proceeds stereoselectively to provide a multi-functionalized spiro[4.5]decane, which is an efficient precursor for
基于在烯基双环二氢吡喃体系中的克莱森重排,完成了(±)-α-香螺碳烯,(±)-海索酚和(±)-β-香根酮的立体选择性全部合成。该方法最显着的特征是双环二氢吡喃的克莱森重排选择性进行,以提供多功能的螺[4.5]癸烷,这是合成香根草倍半萜的有效前体。
