Facile Synthesis of Benzimidazo[2,1-a]isoindoles from Phenolic Adducts of Ninhydrin
摘要:
An efficient synthesis of substituted benzimidazo[2,1-a]isoindoles via the reaction of phenolic adducts of ninhydrin with o-phenylenediamine in Et0H/AcOH under reflux conditions is achieved in single step. The process involves acid-catalyzed rearrangement followed by reaction with o-phenylenediamine.

A simple, facile, one-pot procedure for the synthesis of substituted benzodiazonines from phenolic adducts of ninhydrin is described. The process involves a base-catalyzed rearrangement followed by condensation of 1,3-propanediamine to furnish nine-membered heterocyclic ring system.
