    摘要: Desalaninebenanomicin A has been synthesized by chemical conversion of benanomicin A. Amino acid derivatives of desalaninebenanomicin A having the general formula (Ia): ##STR1## where R.sup.a represents a hyhrogen atom, a C.sub.1-5 alkyl group, a C.sub.1-5 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 R.sup.a is a C.sub.2-5 alkyl group, a C.sub.2-5 hydroxyalkyl group, carboxyl group or a lower alkoxycarbonyl group are novel semi-synthetic antibiotics having antifungal activities.
