The chemistry of prasinons A and B. Identification of the nitrogen-containing moiety
Abstract
Hydrogenolysis of prasinon B, an insecticidal metabolite of Streptomyces prasinus, gave N-2-(1,3-dioxocyclopentyl)-succinamic acid, the methyl ester of which (dihydroflavensomycinic acid) is a known degradation product of the antibiotic flavensomycin. The relationship between flavensomycin and the prasinons is discussed.
