Hydrogen-bonding organocatalysts L-pyroglutamic sulphonamides were readily synthesized for the first time by fully exploiting the potentials of L-pyroglutamic acid. The newly designed catalyst was successfully applied in catalyzing asymmetric Diels-Alder

A broad range of pyrroloimidazolediones, new highly functionalized bicyclic heterocycles, was obtained by a cycloaddition reaction between L-pyroglutamide derivatives and Bredereck's reagent. Methanolysis of subsequent pyrroloimidazolediones provided antagonists of P2X7 receptor, with retention of initial stereoconfiguration, with potential applications in the treatment of inflammatory and neurological diseases. We have thus developed a new synthesis of lactamic nitrogen free enaminones which is currently the easiest method cited in the literature to access these compounds.
