ABSTRACT:
New antibacterial tetronolide compounds F-1 and F-2 are produced by fermentation of a microorganism belonging to the genus Micromonospora. The antibiotics F-1 and F-2 are accumulated in the culture liquor and are isolated therefrom respectively and the acyl derivatives of F-1 and F-2, that is, F-1-21-O-acetate, F-1-21-O-propionate, F-1-21-O-n-butylate, F-1 diacetate, F-1 dipropionate, F-2 triacetate, F-2 tripropionate and F-2 tri-n-butylate, etc., are synthesized from F-1 and F-2 by known means.
