A totalsynthesis of the proposed structure 1 for the oxazoline/thiazoline-based cyclopeptide cyclodidemnamide, isolated from the sea squirt Didemnum molle, is described. The synthesis features a novel double cyclodehydration, sequential formation of chiral thiazoline and oxazoline rings in a preformed cyclopeptide intermediate, as a key stratagem. The NMR spectroscopic data for synthetic 1 and natural
