Organosulfurs are important commodity chemicals and indispensable synthetic intermediates in modern chemistry that were traditionally synthesized using metal catalysts, oxidants or strong bases, which caused numerous environmental pollution issues. The divergent synthesis of these scaffolds via a single catalysis under catalyst and oxidant free conditions is a fantastic idea to overcome these drawbacks
有机硫是现代化学中重要的大宗化学品和不可缺少的合成中间体,传统上采用金属催化剂、氧化剂或强碱合成,造成了诸多环境污染问题。这些支架的不同合成通过在无催化剂和无氧化剂条件下的单一催化是克服这些缺点的绝妙想法。在这里,我们报告了一种安全、实用和环保的电化学方法,用于 1,2-二氯乙烷 (DCE) 与硫醇的可控脱氯偶联,提供增值的 β-氯乙基硫,作为高效后期的通用构件。 -阶段转化为生物活性分子。该协议的温和性和实用性进一步证明了抗痛风药物磺吡酮的全合成,三步总收率为 32%。
