描述了一种可见光光氧化催化碳自由基介导的2-乙烯基苯酚原位生成邻醌的策略。这一策略使2-乙烯基苯酚、Umemoto试剂和硫酰化物的多组分环化反应成为可能，从而获得三氟甲基化的2,3-二氢苯并呋喃。
A visible light photoredox-catalyzed carbon radical-mediated strategy for in situ formation of ortho-quinone methides from 2-vinyl phenols is described. This strategy enables a multicomponent cyclization reaction of 2-vinyl phenols, Umemoto's reagent, and sulfur ylides, providing access to trifluoromethylated 2,3-dihydrobenzofurans.
