β¦ Synopsis
As a result of the x-ray single crystal analysis of N-iodoacetylamphotericin B the chemical and stereochemical absolute structure ia presented (I). A similar etructure and stereochemistry wae extended to the parent compound itself, amphotericin B, a heptaene macrolide antifungal antibiotic possessing a free amino group in the sugar moiety. The configuration of the asymmetric centers of the macrolide lactone ring based on the absolute stereochemistry of mycosamine 1,2 are given under the Cahn-Ingold-Prelog system'
in Table 1.
