base. The developed methodology has been applied to the stereoselective coupling of primary, secondary, and tertiary alkyl radicals with (hetero)aromatic terminal alkynes. As an additional practicality, similar reaction conditions allowed for the use of aromatic amines as radical precursors in a cross dehydrogenative coupling for the direct vinylation of inactivated C–H bonds.
已经开发了用于从
羧酸和
炔烃合成各种
烯丙基胺和醚的光氧化还原策略。这种方法依赖于通过炔基
铜中间体的形成和光激发对末端
炔烃基态电子特性的扰动。该过程通过
铜和有机光氧化还原的协同催化进行,并且可以立体发散的方式进行。因此,系统的多变量HTE筛选显示,通过选择合适的
配体和碱基组合,可以引起立体
化学结果的改变。所开发的方法已应用于伯,仲和叔烷基与(杂)芳族末端炔的立体选择性偶联。另外,
