Base‐Mediated Synthesis of Sulfur‐Substituted Imides using N‐(acyloxy)‐Tetrachlorophthalimides/Anhydrides and Alkyl Isothiouronium Salts

European Journal of Organic Chemistry, Volume 29, Issue 19, 22 May 2026.
An efficient, scalable, and versatile base‐triggered synthesis of sulfur‐substituted imides with the utility of alkyl isothiouronium salts and masked carboxylic acids under mild reaction conditions. Imides have a vast presence in pharmaceuticals and natural products, and their synthesis generally relies on the utility of the disagreeable strong ...
