An efficient, green and sustainable approach for the synthesis of novel polycyclic pyrrolidine-fused spirooxindole compounds was developed. The synthesis included a one-pot, three-component, domino reaction of (E)-3-(2-nitrovinyl)-indoles, isatins and chiral polycyclic α-amino acids under catalyst-free conditions at room temperature in EtOH–H2O. The salient features of this methodology are eco-friendliness
开发了一种高效、绿色和可持续的新型多环吡咯烷稠合螺氧吲哚化合物的合成方法。该合成包括 ( E )-3-(2-硝基乙烯基)-吲哚、靛红和手性多环 α-氨基酸在室温下在 EtOH-H 2中在无催化剂条件下的一锅三组分多米诺反应O. 该方法的显着特点是生态友好、高收率以及在不涉及有毒溶剂和柱层析的情况下易于获得目标化合物。这些新型多环吡咯烷稠合螺氧吲哚提供了一系列结构多样的化合物,这些化合物有望用于未来的生物测定和医学治疗。
