ABSTRACT: A convergent diastereo- and enantioselective total synthesis of anti-HIV agent chloropeptin I (I) is reported. Important features of the total synthesis include: (1) the use of titanium-catalyzed cyanide addn. to imines to prep. a requisite amino acid moiety, (2) the discovery of the pos. effect of MeOH in the Cu-mediated biaryl ether formation to afford one of the two macrocyclic peptide moieties, and (3) the discovery of the pos. influence of collidine in the diastereoselective Pd-mediated cross-coupling to result in efficient formation of another macrocycle within this medicinally important mol. This key step is performed in the presence of four unprotected phenols, two of which reside on dichlorophenylglycines.
