The orcinol series The most conunon fate of acetate-polymalonate-derived phenolic acids in lichens is intermolecular esterification of two or three similar or identical units. For example, the carboxylic acid of one unit is joined to the hydroxyl para to the carboxylic acid of the second unit. Such esterifications lead to the para-depsides. A second esterification reaction leads to tridepsides. If an ester linkage joins the first unit to a position meta to the carboxylic acid of the second ring, a weta-depside results. [Pg.10]

The major structural variations observed in the orcinol para-depsides (204) are the length of the polyketide-derived side chains (R, R ), the degree of oxidation of these side chains (CH2COR or CH2CH2R) and the degree of methylation of the phenolic and carboxyl groups (R, R , R, R = Me or H). [Pg.143]
