The present invention is intended to provide a method for efficiently producing and providing a compound having a spirooxindole skeleton, for example, a compound having a spirooxindole skeleton and having antitumor activity that inhibits the interaction between Mdm2 protein and p53 protein, or an intermediate thereof, using an asymmetric catalyst. A compound having an optically active tricyclic dispiroindole skeleton is efficiently obtained through a catalytic asymmetric 1,3-dipolar cycloaddition reaction using ketimine as a reaction substrate and using a chiral ligand and a Lewis acid.
本发明旨在提供一种有效生产和提供具有螺环氧吲哚骨架的化合物的方法,例如,利用不对称催化剂制备具有螺环氧吲哚骨架并具有抗肿瘤活性的化合物,该化合物抑制Mdm2蛋白与p53蛋白之间的相互作用,或其中间体。通过使用酮亚胺作为反应底物,并使用手性配体和Lewis酸进行催化不对称1,3-二极环加成反应,有效地获得具有光学活性的三环二螺吲哚骨架的化合物。
