Abstract

L'Acido 3-(L-piroglutamil)-L-tiazolidin-4-carbossilico e i suoi derivati vengono sintetizzati con rese quantitative attraverso un processo di condensazione fra acido L-piroglutammico o suoi prodotti di sostituzione in presenza di solvente idrocarburico alifatico o aromatico o di solventi clorurati in presenza di dicicloesilcarbodimmide o similari, o per condensazione di derivati attivi di acido L-piroglutammico con derivati dell'acido tiazolidin-4-carbossilico. L'idrolisi dei gruppi protettivi dell'acido tiazolidin-4-carbossilico avviene a mezzo di catalizzatori di trasferimento di fase con rese quantitative.3- (L-pyroglutamyl) -L-thiazolidin-4-carboxylic acid and its derivatives are synthesized with quantitative yields through a process of condensation between L-pyroglutamic acid or its replacement products in the presence of an aliphatic or aromatic hydrocarbon solvent or of chlorinated solvents in the presence of dicyclohexylcarbodimide or the like, or by condensation of active derivatives of L-pyroglutamic acid with derivatives of thiazolidin-4-carboxylic acid. The hydrolysis of the protective groups of thiazolidin-4-carboxylic acid occurs by means of phase transfer catalysts with quantitative yields.
