Reassignment of the Structure of the Antibiotic A53868 Reveals an Unusual Amino Dehydrophosphonic Acid

Abstract

Third time's the charm! The structure of the phosphonate antibiotic A53868, first isolated in 1983 from Streptomyces luridus, has proven quite elusive. Originally reported as 1 and later revised to 2, the actual structure of the compound is the unusual dehydro aminophosphonic acid 3.
