Metal‐Free Selective and Diverse Synthesis of Three Distinct Sets of Isoindolinones from 2‐Alkynylbenzoic Acids and Amines.

The metal‐free selective and diverse synthesis of three distinct sets of isoindolinones from 2‐alkynylbenzoic acids and amines has been achieved in a reaction‐condition‐controlled manner. This method exhibits valuable advantageous features such as available starting materials, broad substrate scope, excellent selectivity, good to high yields, good functional group tolerance, simple operation, high bond‐forming efficiency, and step economy, thus providing a convenient and efficient access to a variety of heterocyclic compounds incorporating the bioactive isoindolinone motif.
