A novel multi-component reaction (MCR) of oxo-components, primary amines, thiocarboxylic acids and 3-bromo-2-isocyanoacrylates yielding 2,4,5-trisubstituted thiazole building blocks is described.
Stereoselective β-brominationofN-formyl-α, β-dehydroaminoacid esters5 was investigated. A reaction of5 with NBS affordedα-bromo-N-formylimines10 which successively isomerized to giveβ-bromo-N-formyl-α, β-dehydroaminoacid esters4. The migration of the double bond of the intermediates10 with bulky substituents at the β-position resulted in highly stereoselective formation of(Z)-4, while that of the

We report a second example of a general reaction screening approach to discover low molecular weight inhibitors of protein protein interactions. On the basis of the known pharmacophore model of SMAC mimetics, we predicted several inhibitors based on four different multicomponent reactions. The predicted inhibitors were subsequently synthesized, tested, and found to bind to the antiapoptotic protein X-linked inhibitor of apoptosis protein (XIAP) and showed cellular activity. Also the compounds are currently not highly potent. They could form a starting point for future medicinal chemistry optimization.

A novel synthetic method for methyl 5-substituted thiazole-4-carboxylates (5) by the reaction of methyl 3-substituted 3-bromo-2-isocyanoacrylates(BICA)(1) with hydrogen sulfide in the presence of triethylamine in N,N-dimethylformamide was explored, and the reaction mechanism was elucidated.
