A new highly selective synthesis of amides and carbamates is described. In both cases the syntheses involve the formation of carbonyl imidazole intermediates which subsequently undergo previously unreported selective reactions with primary amines. Acid imidazolides with sufficient chain length will exclusively react with primary amines even in the presence of secondary and tertiary functionality. The

The present invention relates to novel diurea derivatives that block intracellular signal transduction and thereby inhibit the production of pro-inflammatory cytokines, especially interleukin-2 (IL-2) and/or induce apoptosis in activated T-cells. It further discloses such a compound for use as a medicament, the use of said compound for the manufacturing of a medicament for the treatment of immune disorders which benefit from inhibition of production of IL-2 and other pro-inflammatory cytokines and/or induction of apoptosis in activated T-cells, a pharmaceutical composition comprising said compound and a method of treatment comprising administration of a pharmaceutically effective amount of said compound. A compound of the general formula I.
