An efficient one-pot four-component synthesis of 1H-pyrazolo[1,2-b] phthalazine-5,10-dione derivatives catalyzed by proline

The present report articulates a potential and green method for the synthesis of pyrazolo[1,2-b]phthalazine-5,10-dione by one-pot four component reaction involving phthalimide (1), hydrazine hydrate (2), aldehyde (3) and malononitrile (4). Proline has been utilized as organo-catalyst in a mixed solvent of ethanol and water in the ratio of 2:1 at 80 degrees C. The reaction reveals excellent reactivity, functional group tolerance, and quite high yields without using any extreme reaction condition like strong acid or metal catalyst. Eighteen compounds have been synthesised by this method including five new compounds.

Access to a Phthalazine Derivative Through an Angular cis-Quinacridone

Intramolecular electrophilic cyclization of a bisanthranilate afforded an angular cis-quinacridone compound, which condensed with hydrazine to give a phthalazine derivative. A [2+2+2] cyclization reaction occurred at the C-N double bond position of phthalazine when reacted with dimethyl acetylenedicarboxylate. The structures of these novel compounds were confirmed by crystallographic analysis. The phthalazine derivative decomposes back to quinacridone at ambient condition in the dark and as a solid with a half lifetime of about 22 months.

5-Sulphosalicylic acid: An expeditious organocatalyst for one-pot synthesis of 2H-indazolo[2,1-b]phthalazine-triones

Green and atom economic protocol has been developed for one-pot, multi-component synthesis of 2H-indazolo[2,1-b]phthalazine-triones in presence of 5-sulphosalicylic acid as an organocatalyst under solvent-free conditions. Non-toxic, cost-effective catalyst, high yields, shorter reaction times, simple experimental and work-up procedure are salient features of our synthetic route. [GRAPHICS]
