We developed a highly regioselective base-induced synthesis of N2-substituted 1,2,3-triazoles from N-sulfonyl-1,2,3-triazoles and alkyl bromides/alkyl iodides at room temperature. We propose an SN2-like mechanistic pathway to explain the high N2-regioselectivity. The protocol features a broad substrate scope and generates products in good to excellent yields (72–90%).
我们开发了一种在室温下由N-磺酰基-1,2,3-三唑和烷基溴/烷基碘合成N 2 -取代的 1,2,3-三唑的高度区域选择性碱诱导合成。我们提出了一种类似 S N 2 的机制途径来解释高N 2区域选择性。该协议具有广泛的底物范围,并以良好的产量产生产品 (72–90%)。
