Reductive and halogenative Barton decar☐ylation methodologies provide an expeditious access to variously 1,6-di- and 1,6,11,16-tetrasubstituted pentagonal dodecahedranes. Vicinal CO2R and Cl substituents cause increasing competition in the radical transfer step.
还原性和卤化的Barton
十烷基化方法可快速获得各种1,6-二-和1,6,11,16-四取代的五角形十二面体。相邻的CO 2 R和Cl取代基会在自由基转移步骤中引起越来越多的竞争。
