We report here a regiospecific [3 + 2] annulation between aminocyclopropanes and various functionalized alkynes enabled by a P/N-heteroleptic Cu(I) photosensitizer under photoredox catalysis conditions. Thus, a divergent construction of 3-aminocyclopentene derivatives including methylsulfonyl-, arylsulfonyl-, chloro-, ester-, and trifluoromethyl-functionalized aminocyclopentenes could be achieved with
我们在这里报告了在光氧化还原催化条件下,由P / N -杂配 Cu(I) 光敏剂实现的氨基环丙烷和各种功能化炔烃之间的区域特异性 [3 + 2] 环化。因此,可以实现 3-氨基环戊烯衍生物的发散结构,包括甲基磺酰基-、芳基磺酰基-、氯-、酯-和三氟甲基-官能化的氨基环戊烯,具有高区域选择性、广泛的底物相容性以及温和和环境友好的反应条件等优点。
