The enantioselective synthesis of (S)-(+)-tylophorine, a potent cancer cell growth inhibitor, has been accomplished in eight steps from commercially available 3,4-dimethoxybenzyl alcohol. A copper (II)-catalyzed enantioselective intramolecular alkene carboamination was employed as the key step to construct the chiral indolizidine ring.
( S )-(+)-tylophorine 是一种有效的癌细胞生长抑制剂,它的对映选择性合成是从市售的 3,4-二甲氧基苯甲醇分八步完成的。铜 (II) 催化的对映选择性分子内烯烃碳胺化被用作构建手性吲哚里西啶环的关键步骤。
