A circular dichroic method for determining the linkage to symmetric hexocyclitols and hexocyclitolamines; structure of two antibiotics from Nocardia sp.
Abstract
A highly sensitive c.d. method which appears to have general applicability has been developed to determine the point of attachment of substituents on symmetric hexocyclitolamine and hexocyclitol residues; it has been applied in the structure determination of two antibiotics LL-BM 123α and LL-BM 782α2.
