The radical 3, generated (i) from reactions of 5-substituted 2-tert-butyl-1,3-dioxolan-4-ones with N-bromosuccinimide, (ii) from related bromo compounds by reaction with tributylstannane or with allyltributyltin, and (iii) by radical addition to 5-methylene-1,3-dioxolan-4-one, undergoes carbon-bromine, carbon-hydrogen, and carbon-carbon bond formation trans to the tert-butyl group with moderate to
基团3,(i)由5-取代的2-叔丁基-1,3-二氧戊环-4-酮与N-溴代琥珀酰亚胺反应生成,(ii)由相关的溴化合物与三丁基锡烷或烯丙基三丁基锡反应生成,和(iii)通过自由基加成至5-亚甲基-1,3-二氧戊环-4-酮,进行碳-溴,碳-氢和碳-碳键的形成,以中等至高的非对映选择性转化为叔丁基。
