synthesis of cyclicsulfinates and sulfinamides based on intramolecular homolyticsubstitution (SHi) at the sulfuratom by aryl or alkyl radicals is described. Both alkyl and benzofused compounds can be accessed directly from easily prepared acyclic precursors. Enantiomerically enriched sulfur‐based heterocycles were formed through an SHi process with inversion of configuration at the sulfuratom. Cyclization
描述了基于在硫原子上被芳基或烷基自由基的分子内均质取代(S H i)合成环状亚磺酸酯和亚磺酰胺的通用且有效的方法。烷基和苯并稠合的化合物都可以直接从容易制备的无环前体中获得。对映体富集的硫基杂环是通过S H i过程形成的,硫原子上的构型反转。前手性自由基的环化进行的立体化学结果各不相同,具体取决于传入自由基的大小。2-吡啶基和2-喹啉基会生成联芳基化合物,这是由于攻击芳基亚磺酸盐的邻位而不是亲硫取代引起的。
