Abstract

Structures for two new acylpholorglucinols, myrtucommulone A (1) and myrtucommulone B (2) have been deduced from a detailed study of the NMR, IR and mass spectra of these substances, and their simple derivatives and degradation products. The compounds contain phloroglucinol and syncarpic acid (1,1,3,3, tetramethyl-cyclohexa-2,4,6-trione) residues, and are closely related chemically to fern constituents such as filixic acid, as well as to kosins and uliginosins isolated from higher plants. Compounds 1 and 2 are unique in having an isobutyl bridge connecting the rings. Compound 1 exhibits strong antibacterial activity against gram positive bacteria.
