ChemistryEurope, Volume 4, Issue 3, March 2026.Chiral gem‐dicyano‐spirocyclopropyl oxindoles are obtained by a chiral N‐9‐Anth‐PyBidine‐Co(OAc)2‐catalyzed asymmetric Michael/alkylation reaction of 3‐chlorooxindoles with alkylidenemalononitriles. The three‐component coupling reaction of 3‐chlorooxindoles, aldehydes, and malononitrile shows the advantage of not requiring the preparation of ...
