ONE-STAGE SYNTHESIS OF INDANONES IN THE BENZIMIDAZOLIN-2-ONE SERIES

Article abstract of DOI:10.1007/BF00579774

The possibility has been shown of a one-stage synthesis of 5,6-ureylene-3-methylindan-1-one and 6,7-ureylene-3,5-dimethylindan-1-one by condensing the corresponding benzimidazolin-2-ones with γ-butyrolactone ar crotonic acid in the presence of aluminum chloride.The reaction was performed at a ratio of the reactants benzimidazolin-2-one (5-methylbenzimidazolin-2-one): γ-butyrolactone (crotonic acid): AlCl3=1:1:6.Several derivatives (oximes, semicarbazones, substituted hydrazones) have been obtained that confirm the ketonic structures of the indanones synthesized.The plant growth inhibiting and fungicidal activities of the compounds synthesized have been studied.
