Synthetic studies on antibiotic validamycins. Part 13. Total synthesis of (+)-validamycins A and E, and related compounds

(+)-Validoxylamine A (1) has been completely synthesized by deoxygenation of the validoxylamine B derivative (6) through formation of the aziridine, nucleophilic displacement with toluenethiol, reduction with Raney nickel, and deprotection. The validoxylamine A derivative (10) obtained was convertible, by glycosylation followed by deprotection, into validamycins A (2), E (3), and their analogues, which constitutes a total synthesis thereof.

Total Synthesis of (+)-Validoxylamine A

(+)-Validoxylamine A was synthesized by selective deoxygenation of (+)-validoxylamine B derivative, which was obtained by the coupling of the partially protected (+)-valienamine and (1R,2S,5R,7R,8R,9R,10R)-8,9-dibenzyloxy-5-phenyl-4,6,11-trioxatricyclo8.
