the synthesis of mono-, bis- and tris-2,4-disubstituted oxazoles were evaluated, which led ultimately to a concise synthesis of the three contiguous oxazole ringsystem 26 in the ulapualide family of 25-membered macrolides, e.g.1, found in marine organisms. The tris-oxazole macrolide core 30 in ulapualide A (1) was also synthesised based on a macrolactamisation strategy from the two functionalised mono-oxazole

A series of thiazolyl-oxazoles, most of them having the structural feature NCCN of 2,2′-bipyridyl known to form metal chelates, has been synthesized by condensation of α-halogen carbonyl compounds with thioamides of oxazole-carboxylic acids. The latter were obtained by the method of CORNFORTH and by preparing successively their esters, amides, and nitriles.
