A variety of spirocyclic heterocycles have been constructed by a double-alkylation and reductive cyclization approach utilizing α-heteroatom nitriles as trianion synthons. The method provides access to heteroatom-substituted spirocycles in a variety of ring sizes that are found in natural products and are important in pharmaceutical lead development and optimization.
利用α-杂原子腈作为三阴离子合成子,通过双烷基化和还原环化方法构建了多种螺环杂环。该方法提供了获得各种环大小的杂原子取代螺环的途径,这些环大小在天然产物中发现并且在药物先导开发和优化中很重要。
