Biosynthesis of primin and miconidin and its derivatives

Numerous 2-methoxy-6-n-alkyl-1,4-benzoquinones with interesting biological activities have been found as constituents of plants and plant seeds. The most prominent is primin, the n-pentyl derivative, which is stored in trichomes on leaves and stems of Primula obconica and is responsible for primrose dermatitis. The biosynthesis of primin was studied by feeding experiments with radioactively labelled precursors and unlabelled homologues. Copyright

BIOLOGICALLY ACTIVE PHENOLIC METABOLITES OF A VERTICICLADIELLA SPECIES

The metabolites produced when a Verticicladiella species (Canadian Forestry Service strain C728), the causative agent of the black stain root disease of many conifers, is grown in liquid culture have been investigated.Orcinol, orcinol monomethyl ether, 1,3,6,8-tetrahydroxyanthraquinone, and the α-L-rhamnopyranosides of orcinol and orcinol methyl ether have been isolated and indentified.Orcinol methyl ether and its rhamnoside both show antibacterial activity and orcinol methyl ether also inhibits the growth of pine germlings.The general antibacterial activity of 5-alkylresorcinols and their monomethyl ethers is reported.-Key Word Index-Verticicladiella sp.; Deuteromycontina; blue-stain fungus; phytotoxin; phenols; methylorcinol rhamnoside; phenol monomethyl ethers; antiseptics.

ISOMERISATION OF ο-ALKENYL SUBSTITUTED CYCLOHEXANE-1,3-DIONE ENOL DERIVATES USING RHODIUM CATALYSIS. A PRACTICAL SYNTHESIS OF SUBSTITUTED RESORCINOLS

Treatment of the ο-alkenyl substituted cyclohexane-1,3-dione enol derivates (1), (11), and (13) with rhodium trichloride trihydrate leads to the corresponding resorcinol derivates (2), (12), and (15) respectively.By contrast, the RhCl3.3H2O catalysed isomerisations of the related enol ethers (5) and (9) instead produce the dienones (6) and (10) respectively.
