The Ajudazols A and B, Novel Isochromanones from Chondromyces crocatus (Myxobacteria): Isolation and Structure Elucidation

摘要

Two novel metabolites, ajudazols A (1) and B (2), were isolated in a screening of the myxobacterial genus Chondromyces from several strains of C. crocatus. Both 1 and 2 are unique isochromanone derivatives with an extended side chain containing an oxazole, a Z,Z-diene, and a 3-methyoxybutenoic acid amide as characteristic structural features.
