title: Chemical modifications of bafilomycin-type 16-membered dienlactone macrolides.
abstract: Derivatives of the 16-membered dienlactone bafilomycins were prepared in order to study the structure-activity relationship of these compounds. Some derivatives formed by hydrolysis, O-alkylation, O-acylation, trans-esterification and epoxidation were isolated and their structures determined by two-dimensional (2D) NMR studies and mass spectroscopy.
