An efficient, eco-friendly protocol is developed for the synthesis of 1- (α-aminoalkyl)-2-naphthol derivatives via one-pot three-component reaction of 2-naphthol, aromatic aldehydes and piperidine or morpholine in the presence of Amberlite IRA-400 Cl resin as a catalyst. This approach carries characteristics of one-pot synthesis, high yield, and mild, clean reaction conditions with the recyclable catalyst
开发了一种高效、环保的协议,用于在 Amberlite IRA 存在下,通过 2-萘酚、芳香醛和哌啶或吗啉的一锅三组分反应合成 1-(α-氨基烷基)-2-萘酚衍生物-400 Cl树脂作催化剂。该方法具有一锅法合成、收率高、反应条件温和、清洁的特点,催化剂可回收利用。得到其中一种产物(4p),在具有 P32 空间群的三角晶系中结晶,并与流行的密度泛函理论(DFT)、B3LYP/6-311++G(d,p) 基组的理论计算进行比较. 计算了最高占据分子轨道(HOMO)和最低未占据分子轨道(LUMO)的能量。所有理论计算与实验值一致。
