Abstract

The absolute configurations of two new immunosuppressants, mycestericins E (1) and G (2), were establishied and both compounds were synthesized starting from 1, 8-octanediol and a fully protected methyl (2S, 4R)-oxazolidine-4-carboxylate 3. Compounds 5 and 22, with a (l'R)-hydroxyl group, were prepared from the β-keto esters 4 and 21, respectively, by stereoselective reduction with metal borohydrides.
