    摘要: Macrolide antibiotics are derivatives of the compound Mycoplanecin and have the formula: ##STR1## (in which R represents a hydrogen atom or an N-(.alpha.-hydroxybutyryl)-N-methylvalyl group). The compound in which R represents an N-(.alpha.-hydroxybutyryl)-N-methylvalyl group can be prepared by reducing Mycoplanecin and the compound in which R represents a hydrogen atom can be prepared by the hydrolysis of Mycoplanecin or of the compound of formula (I) in which R represents an N-(.alpha.-hydroxybutyryl)-N-methylvalyl group.
