Palladium-catalyzed domino Heck/cyanation: Synthesis of 3-cyanomethyloxindoles and their conversion to spirooxoindoles

Jaegli, Stéphanie,Vors, Jean-Pierre,Neuville, Luc,Zhu, Jieping

experimental part, p. 8911 - 8921 (2011/02/22)

3′-Alkyl-3-cyanomethyloxindoles, prepared by a palladium-catalyzed domino Heck/cyanation, were efficiently converted to spiropyrrolidinyl-, spiropiperidinyl- and spirocyclopropyl-oxindoles. The so-obtained spirooxindoles bearing three diversity points wer
