In a article, author is Maheshwari, D. P. Loka, introduce new discover of the category.
One-pot, four component syntheses for the preparation of 1-H Pyrazolo[1,2-b]phthalazine-5,10-diones (5a-5h) have been achieved from phthaloyl dichloride (1), hydrazine hydrate (2), benzaldehydes (3) and malononitrile (4a) or ethyl cynoacetate (4b) in molten Tetrabutylammonium Bromide as medium at 100-105 degrees C for 20-30 min by in-situ generation of HCl as a catalyst. These reactions have an easy workup, provide excellent yields, and use TBAB as the reaction medium.
