Cytotoxic Prenylated Depsidones from Garcinia parvifolia

Journal of Natural Products, 2000
Leaf extracts of Garcinia parvifolia provided relatively high yields of four novel, cytotoxic prenylated depsidones. The structures were determined mainly by detailed NMR spectral analysis and X-ray crystallography.

Depsidone synthesis. Part 15. New metabolites of the lichen Buellia canescens(Dicks.) De Not: novel phthalide catabolites of depsidones

Journal of the Chemical Society, Perkin Transactions 1, 1981
The isolation, from the lichen Buellia canescens(Dicks.) De Not., and structural determination of the new depsidones 2,7,9-trichloro-3-hydroxy-8-methoxy-1,6-dimethyldibenzo[b,e][1,4]dioxepin-11-one (dechlorodiploicin)(1) and its methyl ether dechloro-O-methyldiploicin (9), together with the novel phthalides 4-chloro-7-(3,5-dichloro-4,6-dimethoxy-2 ...

A theory of biogenesis of lichen depsides and depsidones

Proceedings of the Indian Academy of Sciences - Section A, 1944
Lichen depsides and depsidones are considered to arise from a common source (XIV) which originates from aldol condensation between a hexose and a biose and elimination of water. Oxidation and reduction lead to various modifications of this C8 unit and increase in the length of the sidechain arises from condensation with simple sugars and reduction ...
