Popis: | A short synthesis of the novel antibiotic aranorosin in chiral form is described which employs (i) a novel hypervalent iodine-mediated oxidative hydroxylation of a tyrosinal derivative and (ii) a stereocontrolled cis-bisepoxidation in the key steps. A similar procedure was employed to prepare 6′-epiaranorosin, and hence establish the stereochemistry of the natural compound, and to prepare novel aranorosin analogues. An organometallic route is described which gives desamidoaranorosin. |
