ONE-POT FOUR COMPONENT REACTION FOR THE SYNTHESIS OF 1-(1H-INDOL-2-YL)-1H-PYRAZOLO [1,2-b]PHTHALAZINE-5,10-DIONE DERIVATIVES BY SELF-CATALYSIS
In this, we performed a four component domino reaction of phthaloyl dichloride, hydrazine hydrate, indole-3-carboxaldehydes and malononitrile/ethyl cyanoacetate to form 1-(1H-indol-2-yl)-1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives by in situ generation of HCl as catalyst in refluxing ethanol for 1 h in good yields. This four component domino reaction transformation presumably proceeds via addition/dehydrohalogenation/condensation/cyclization of reactions. The material was thoroughly characterized at various stages of its formation by means of FTIR, NMR spectroscopic and Mass spectrometric analysis and is confirmed to be the derivative of 1-(1H-indo1-2-yl)-1H-pyrazolo [1,2-b]phthalazine-5,10-dione.
