A generally useful Ni(II)/trisoxazoline-catalyzed asymmetric sulfa-Michael/Aldol cascade reaction is introduced to access chiral 3-amine-tetrahydrothiophene derivatives containing a quaternary stereocenter (32 examples, up to 93% yield, > 20:1 dr and 92% ee). Moreover, the novel strategy offers an efficient and convenient approach to construct chiral thionucleoside analogues.
本文介绍了一种普遍适用的 Ni(II)/三恶唑啉催化的不对称砜-迈克尔/Aldol 级联反应，用于获得含有季立体中心的手性 3-胺四氢噻吩衍生物（32 个例子，最高产率达 93%，>20:1 dr 和 92%ee）。此外，该新策略提供了一种高效、便捷的方法来构建手性硫核苷类似物。
