Abstract

A process for the preparation of an everninomycin derivative of the general formula i ** (see formula) ** And pharmaceutically acceptable salts thereof, wherein x represents a nitroso group, a hydroxylamino group or a nitrone group capable of being derived from the hydroxylamino group, y represents hydrogen or a hydroxy group and z represents the group (see formula) when y is hydroxy, and represents hydrogen or (see formula) when y is hydrogen, characterized in that a starting material of everninomycin b, c or d is reduced in the nitro group and, if desired, a hydroxylamino derivative thus obtained is converted into the corresponding nitrona derivative, the derivative being isolated hydroxylamino, nitroso or nitrona required as such or in the form of a pharmaceutically acceptable salt.
