APPLICATION OF SCHOTTEN–BAUMANN AND GABRIEL- MICHAEL REACTION FOR SYNTHESIS OF NOVEL PHTHALAZINE DERIVATIVES ANWENDUNG Schotten-Baumann-UND GABRIEL-Michael-Reaktion FüR Synthese neuartiger PHTHALAZINE DERIVATE

A simple and convenient procedure has been developed for the synthesis of Novel 1- phthalazinone and 1, 4-phthalazinedione derivatives using Schotten–Baumann reaction and Gabriel- Michael reaction respectively. All compounds have been characterized by IR, NMR, and MASS spectroscopy.
