stereoselective synthesis of trans-anti-cis decahydro-as-indacene 5 is described. The key step of this synthesis is the tandem Claisen ring contraction of the 16-membered macrolactone 3 followed by the transannular Diels-Alder reaction of the resulting (E,E,E)-cyclododeca-1,6,8-triene 4.
反-反-顺十氢-引达省的立体选择性合成5进行说明。该合成的关键步骤是16元大内酯3的串联Claisen环收缩,然后是生成的(E,E,E)-cyclododeca-1,6,8-三烯4的跨环Diels-Alder反应。
