2,4-5-Trisubstituted Thiazole Building Blocks by a Novel Multi-Component Reac— Substituted thiazoles are synthesized by the new one-pot reaction of carbonyl

compounds with primary amines, thiocarboxylic acids and isocyanides. Using a chiral
amine results in formation of (VIII) with a diastereomeric excess of 71%. The present
procedure is applicable to the total synthesis of certain naturally occurring thiazoles as
well as for combinatorial chemistry. — (UMKEHRER*, M.; KOLB, J.; BURDACK,
