biologically active heterocycles, the asymmetric synthesis of chiral tetrahydroquinolines holds particular importance.3 Selective estrogen receptor modulators (SERMs) constitute a class of biologically active compounds that exert their effects by interacting with estrogen receptors. SERMs have been subjected to extensive research for their potential in treating estrogen-related disorders, such as ovulatory dysfunction
据报道,一种不对称对映选择性流程用于正式合成

雌激素受体调节剂。从容易获得的 2-硝基
查耳酮开始,该过程的第一部分包括使用二
硼酸作为简单还原剂的伸缩硝基还原/分子内环缩合序列。随后在固定化
磷酸有机催化剂存在下进行对映选择性转移氢化,然后进行伸缩式 N-烷基化,得到目标手性中间体。该方法确保了合成规模的灵活性,同时最大限度地减少中间纯化的需要并确保环境友好的无
