cyanohydrins through the concomitant construction of three chiral carbon centers is reported. This protocol facilitates the concise synthesis of optically active tetrahydropyran derivatives, which are ubiquitous scaffolds found in various bioactive compounds, through the simultaneous construction of multiple bonds and stereogenic centers, including tetrasubstituted chiral carbons. The resulting products
据报道,通过同时构筑三个手性碳中心,就可以对原位生成的氰醇进行有机催化的对映体和非对映体选择性环醚化。该协议通过同时构建多个键和立体中心(包括四取代的手性碳原子),促进了光学活性四氢吡喃衍生物的简明合成,该衍生物是在各种生物活性化合物中普遍存在的支架。所得产物还包含多个合成上重要的官能团,这些官能团扩展了它们作为手性结构单元的可能用途。
