Elektrophile Reaktionen an der Maleinimiddoppelbindung

Electrophilic Reactions on the Maleimide Double Bond The aminosubstituted maleimides 1 are deprotonated to the anions 2 , which are reacted with various electrophiles. By this way with heterocumulenes, acid chlorides and vinylogous acid chlorides the new acylated maleimides 3 – 6 , 9 , 10 are isolated. This reaction presents a method of direct acylation on the maleimide double bond.
