SYNTHETIC APPROACH TOWARD THE MINIMAL ACTIVE STRUCTURE OF PHOMOPSIN-USTILOXIN CLASS OF ANTIBIOTICS - CONSTRUCTION OF 13-MEMBERED CYCLIC PEPTIDE SKELETON
R. Mutoh et al., SYNTHETIC APPROACH TOWARD THE MINIMAL ACTIVE STRUCTURE OF PHOMOPSIN-USTILOXIN CLASS OF ANTIBIOTICS - CONSTRUCTION OF 13-MEMBERED CYCLIC PEPTIDE SKELETON, Heterocycles, 41(1), 1995, pp. 9-12
The 13-membered cyclic peptides (5a and 5b), the core structure of pho
mopsin-ustiloxin crass of antibiotics, have been synthesized. The fina
l macrolactamization was overcome by the intramolecular aminolysis of
corresponding omega-amino pentafluorophenyl eater.
