Abstract
We report an alternative synthetic approach to annulated diaminopyrimidines based on a one-pot process, in which a Thorpe–Ziegler cyclization of a dinitrile is followed by in situ reaction with a cyanamide under highly concentrated and basic conditions. The total reaction can be carried out as fast as 30 min. The reaction mechanism is discussed. This one-pot synthetic route is universally applicable to a large variety of cyanamides and dinitriles, even natural products, to afford complex annulated diaminopyrimidines.
