A novel solid-phase synthesis towards classical cannabinoids is presented. Starting from immobilized salicylaldehydes the desired THC-analogous tricycles are obtained in four atom-economic steps including cleavage. The reagents of the employed reactions (domino oxa-Michael-aldol, Wittig, and Diels―Alder) can be varied easily, providing the basis for a combinatorial approach. Overall yields range from
提出了一种针对经典大麻素的新型固相合成方法。从固定化的水杨醛开始,通过包括裂解在内的四个原子经济步骤获得所需的 THC 类似三环。所用反应的试剂(多米诺 oxa-Michael-aldol、Wittig 和 Diels-Alder)可以很容易地改变,为组合方法提供了基础。总产率为 20-60%。
