required to facilitate the dehydrogenation and dehydration processes. The key factor in the success was the use of n Bu 4 NBF 4 as the electrolyte and hexafluoroisopropanol (HFIP) as the solvent, which play key roles in the cyclocondensation step. This electrolysis is scalable and can be used as a key step in drug synthesis. On the basis of the several experimental results, the mechanism, particularly
制备电化学合成是建立绿色可持续工艺的理想方法。与传统的化学合成方法相比,有机化学策略的主要优点是避免了试剂浪费和温和的反应条件。在此,已经开发了在不分开的电解条件下,酚与β-二羰基化合物之间的分子间交叉脱氢偶联(CDC),以构建各种苯并呋喃。过渡金属或外部化学氧化剂都不需要以促进脱氢和脱水过程。成功的关键因素是使用n Bu 4 NBF 4作为电解质,使用六氟异丙醇(HFIP)作为溶剂,它们在环缩合步骤中起关键作用。这种电解是可扩展的,可以用作药物合成中的关键步骤。
