and synthetic chemistry. However, the asymmetric construction of chiral quaternary stereocenters bearing both N3 and CF3 groups is still unexplored. Herein, we report a kind of bench-stable and easily adjustable benziodazolone-based azidating reagents. These reagents were used to achieve an enantioselective copper-catalyzed azidation of N-unprotected 3-trifluoromethylated oxindoles to provide diverse
叠氮基 (N 3 ) 和三氟甲基 (CF 3 ) 基团都是许多有价值分子的关键部分,广泛应用于药物发现、化学生物学和合成化学。然而,同时带有 N 3和 CF 3基团的手性四元立构中心的不对称结构仍未得到探索。在此,我们报道了一种稳定且易于调节的基于苯并唑酮的叠氮化试剂。这些试剂用于实现N-未保护的 3-三氟甲基化羟吲哚的对映选择性铜催化叠氮化,以提供多种对映体富集的 3-N 3 -3-CF 3 羟吲哚。
