time. This protocol, merging visible light photoredox and palladium catalysis, provides a direct approach to conjugated tertiary allylic alcohol derivatives with broad functional group tolerance in moderate to excellent yields. Mechanistic studies suggest that, although two possible pathways exist in the transformation, radical oxyalkenylation promoted by visible light photoredox takes over the major
首次揭示了次膦基烯丙基的高度区域和立体选择性的氧烯基化。该协议,结合了可见光的光氧化还原和钯催化作用,提供了一种直接的方法,以中等到极好的收率,具有宽泛的官能团耐受性的共轭叔烯丙基醇衍生物。机理研究表明,尽管转化中存在两个可能的途径,但可见光光氧化还原促进的自由基氧烯基化作用占据了主要途径。
