Synthesis and Characterization of 3-Methylene Isoindolinones by Two Synthetic Routes
Résumé
The aim of this study was a detailed examination of the synthesis of 3-methyleneisoindolinones comprising various functional groups. Methylmagnesuim bromide and PTSA was employed for the synthesis of these compounds. A wide range of 3-methyleneisoindolinones were afforded in good to excellent yields. On the other hand, 3-methyleneisoindolinones was also obtained by an efficient microwave method. The frame work of these derivatives was constructed from 2- acetylbenzoic acid and various primary amines via two-component reaction. The obtained compounds were characterized by 1H NMR, 13C-NMR and IR and elemental analysis.
