The dehydration of maleamicacids using methanesulfonyl chloride as a dehydrating agent to selectively and rapidly (<15 min) generate isomaleimides is reported. A variety of maleamicacid derivatives produce the corresponding isomaleimides in good to excellent yields. Adaptation of this protocol under flow synthesis allows for similar efficiency and decreased reaction times (13 seconds residence time)
