Synthesis of cyclic imides (methylphtalimides, carboxylic acid phtalimides and itaconimides) and evaluation of their antifungal potential

Background: This paper describes the synthesis of three different subfamilies of cyclic imides: methylphtalimides, carboxyl acid phtalimides and itaconimides. Methods: Fifteen compounds (five of each sub-family) were obtained by the reaction of appropriat

An efficient synthesis of dimethylmaleic anhydride

A facile three-step synthesis of dimethylmaleic anhydride (8) with 74% overall yield has been described starting from maleimide 1, via methylmaleimide 4, using two Wittig reactions followed by an alkaline hydrolysis.
