Pseudomonas Pigments. III

Derivatives of Pyoluteorin

抄録

Esters and methyl derivatives of a new pigment pyoluteorin, produced by a strain of Pseudo-monas aeruginosa have been synthesized, and catalytic hydrogenation of the derivatives was carried out to give the corresponding dechloro compounds. It has become clear that pyoluteorin is composed of an unsaturated nucleus and has two phenolic hydroxyls, one amino and the other a cross-conjugated carbonyl group.
