Abstract
Alkaline degradation of rubrofusarin and nor-rubrofusarin were studied; nor-rubrofusarin readily underwent hydrolysis to give a tetrahydroxynaphthalenc, acetone, and acetic acid; whereas, rubrofusarin, after prolonged time of hydrolysis, yielded a β-methoxytrihydroxynaphthalene instead of the naphthol. Physical and chemical studies revealed that the naphthol is 1,3,6,8-tetrahydroxynaphthalene and it has been confirmed by the synthesis from chromotropic acid (disodium salt). Thus, evidently, rubrofusarin has a naphthalene nucleus to which a methoxyl group is attached at β-position. The formation, on the hydrolysis, of acetone and acetic acid, along with the naphthol, indicates the presence of 2-methyl-γ-pyrone structure in rubrofusarin.This publication has 1 reference indexed in Scilit:
