In the first synthesis of a chiral thiazoline-containing macrocyclic peptide, a totalsynthesis of lissoclinamide 4 2c, produced by the marine tunicate Lissoclinum patella, is described.

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
