Abstract

A one-pot, three-component reaction involving SNAr-decarboxylative redox isomerization starting from an electron-withdrawing group bearing fluorobenzaldehyde or fluorothiophenecarbaldehyde (electron-pair diacceptor), secondary amine, and trans-4-hydroxy-l-proline or indoline-2-carboxylic acid (electron-pair donor) has been developed to give N-[(pyrrolylmethyl)-substituted (het)aryl]- and N-[(indolyl­methyl)-substituted (het)aryl]pyrrolidines, -piperidines, -morpholines, and -azocanes. The highlights of this protocol are its great convenience in the simultaneous construction of a C(sp2)–N bond and a C(sp3)–N bond with simple operation; the reaction can be performed on a gram scale. This efficient one-pot multicomponent reaction has potential as a novel method for drug synthesis, especially involving polycyclic compounds.
