P-D-abequoside) has been achieved by use of tris(trimethylsilyl)silane. A new synthesis of methyl p-D-abequoside derivative 16 proceeded via the D-galactose-derived intermediates 14 and 15, and involved deoxygenation at the 6-position by reduction of the tosylate with LAH and at the 3-positions by regioselective opening of the 3,4-cyclic sulfate (Scheme 4). The protected methyl 3,6-dideoxy-a-D-ara6mo-hexopyranoside 17 (methyl a-o-tyvelopyranoside) was similarly obtained by way of an a-o-mannose-derived 2,3-cyclic sulfate 6-tosylate."...

Pradimicins A-C, new antifungal antibiotics, have been isolated from Actinomadura hibisca culture broth they contain a benzo[a] naphthacenequinone chromophore with attached 4-amino-4,6-dideoxy-D-galactose, and, with A and C, a /5-D-xylopyranose glycosidically 0-3 linked to the amino-sugar. N,N-Dimethyl-pradimicins have been synthesized by reductive methylation, which improves water solubility and antifungal activity. ...
