allyloxycarbonyl (Aloc) protectivegroup to avoid the problem. Catalytic amount of Pd in the presence of scavengers such as PhSiH3 and dimedone selectively removed the Aloc group with neither decomposition of the thioester structure nor epimerization at the thioesterified residue. A model pentapeptide and amylin(1‐12) with difficult sequences were efficiently synthesized by the improved S‐acyl isopeptides

Concise and efficient syntheses of optically pure thiazoline and thiazole containing amino acids of the constitution (26) and (27), based on simple condensation reactions between cysteine esters and N-protected imino ethers (22) and (25) derived from chiral amino acids, are described. The synthetic procedures are compatible with a range of amino acid side chains and protecting groups, and allow the
