The total synthesis of the cinnamyl-oxazole substituted tris-thiazoline containing metabolite (-)-thiangazole (1) is described. The synthesis is based on elaboration of the R-2-methylcysteine derived bis-thiazoline nitrile (5) and oxazole (6) intermediates, followed by a cyclocondensation reaction between (5) and (6), and treatment of the resulting tris-thiazoline oxazole ester (16) with methylamine.
