The synthesis of a range of thiazole containing cyclic peptides using cyclooligomerisation reactions of amino acid substituted thiazole monomers and by macrolactamisation procedures is reported. The synthetic approaches lead to high yields of novel 18- and 24-membered ring analogues of the naturally occurring Lissoclinum families of cyclic peptides found in marine organisms and algae.

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

The total synthesis of lissoclinamide 4 and lissoclinamide 5, which are novel oxazoline/thiazole/thiazoline-based cyclopeptides isolatedfrom the ascidian (“sea squirt”) Lissoclinum patella, are described. The synthesis of the bis-thiazole based lissoclinamide 5 necessitated the development of practical solutions to the elaboration of enantiomericallypure valine and phenylalanine substituted thiazoles
