Abstract

Structure Elucidation of Elaiophylin: Spectroscopy and Chemical Degradation The structure of the antibiotic elaiophylin (azalomycin B) was elucidated by extended spectroscopic investigations and chemical degradation. Elaiophylin ( 26 ) is a macrodiolide with a 16membered dilactone ring. The synthesis of 7‐acetoxy‐6‐ethyl‐3‐octanone ( 14 ), the acetyl derivative of an important degradation product, is described.
