formation of optically active highly functionalized tetrahydrothiophenes, which might find important use in biochemistry, pharmaceutical science, and nanoscience is presented. Development of new organocatalytic Michael-aldol domino reactions is outlined, and with the appropriate choice of additives it is possible to control the regioselectivity of these domino reactions, yielding diastereomerically
介绍了一种形成光学活性高官能化四氢噻吩的简单方法,该方法可能在生物化学、药物科学和纳米科学中具有重要用途。概述了新的有机催化迈克尔-Aldol-Aldol-Aldol Domino反应的开发,并且通过适当的添加剂选择,可以控制这些多米诺反应的区域选择性,从产量和良好的产量产生非对映异构纯(四氢噻吩-2-基)苯基甲苯或四氢噻吩碳甲苯具有高达 96% ee 的出色对映选择性。研究了这些反应的立体化学结果,并介绍了这些有机催化多米诺骨牌过程的机制。
