A convergent total synthesis of the ramoplanin A2 and ramoplanose aglycon is disclosed. Three key subunits composed of residues 3−9 (heptapeptide 15), pentadepsipeptide 26, and pentapeptide 34 (residues 10−14) were prepared, sequentially coupled, and cyclized to provide the 49-membered depsipeptide core of the aglycon. Key …

Dale L. Boger* and Douglas S. Johnson Department of Chemistry, The Scripps Research Institute, 10666 North Torrey Pines Road, La Jolla, CA 92037 ABSTRACT Key studies defining the DNA alkylation properties and selectivity of a new class of exceptionally potent, natu-rally occurring antitumor antibiotics in-cluding CC-1065, duocarmycin A, and duo-A team at the Scripps Research Institute in California, led by Dale Boger, has altered the structure of vancomycin, by replacing a carbonyl group by a carbon bound to an NH. In vitro tests show that the modified molecule binds strongly to both normal and resistant bacteria and is effective against both forms.The prize includes a gold medal, certificate and $15,000 award.
