Amphotericin stereochemistry

With all correct stereochemistries now set up, final deprotections and azido group reduction remained to be done in order to obtain the natural antibiotic. The route followed included desilylation, azide reduction, and isopropylidene removal leading to amphotericin B methyl ester which was saponified to the final natural antibiotic la. Both compounds were identical with authentic samples.
