Studies on the New Seventeen Member Lactonic Antibiotics, Bundlins

Part I. The Structures of Bundlin A and B

Abstract

Structural elucidation of the antibiotics bundlin A and B have been accomplished by chemical and spectral results together with three dimensional X-ray structure analysis. The structures of bundlins were consisted of seventeen membered carbon skeleton fused with a six membered lactone system and a pyruvamide side chain.
