Desalaninebenanomicin A has been synthesized by chemical conversion of benanomicin A. Amino acid derivatives of desalaninebenanomicin A having the general formula (Ia): STR1 where Ra represents a hyhrogen atom, a C1-5 alkyl group, a C1-5 hydroxyalkyl group, carboxyl group or a lower alkoxycarbonyl group have been synthesized by condensing the 2-carboxyl group of desalaninebenanomicin A with a variety of amino acids. Among the derivatives of the formula (Ia) having antifungal activities, such desalaninebenanomicin A derivatives in which Ra is a C2-5 alkyl group, a C2-5 hydroxyalkyl group, carboxyl group or a lower alkoxycarbonyl group are novel semi-synthetic antibiotics having antifungal activities.
