Ionophore Antibiotic X-14547A. Degradation Studies and Stereoselective Construction of the "Right Wing" (C11-C25 Fragment) by an Intramolecular Diels-Alder Reaction

Article abstract of DOI:10.1021/jo00320a059

Studies directed toward the total synthesis of the ionophore antibiotic X-14547A are reported.Degradation methods led to a number of "left-wing" fragments, whereas synthetic operations led to a "right- wing" fragment, in a highly efficient and stereoselec
