The invention relates to novel phenethylamide derivatives and their heterocyclic analogues of formula (I), wherein A, B, R1, R2 and R3 are as described in the application, and to the use of such compounds, or of pharmaceutically acceptable salts of such compounds, as medicaments, especially as orexin receptor antagonists.
Mechanism Selection for Regiocontrol in Base-Assisted, Palladium-Catalysed Direct CH Coupling with Halides: First Approach for Oxazole- and Thiazole-4-Carboxylates
Both base‐assisted non‐concerted metallation–deprotonation (nCMD) and concerted metallation–deprotonation (CMD) have been identified as two potent operating mechanisms in palladium‐catalysed direct CH coupling of oxazole and thiazole‐4‐carboxylate esters with halides through base‐ and solvent‐effect experiments. Novel C2‐ and C5‐selective CMD direct arylation procedures in oxazole‐ and thiazole‐4‐carboxylate

A new one-potfour-component preparation of polysubstituted thiazoles by a cascade Ugi/Wittig cyclization has been developed. The four-component reactions of the odorless isocyano(triphenylphosphoranylidene)acetates 1, aldehydes 2, amines 3 and thiocarboxylic acids 4 produced 2,4,5-trisubstituted thiazoles 5 in moderate to good yields in the presence of triethylamine. The two-component reactions between
