Dosage de la chitine sur des ectomycorhizes de pin maritime (Pinus pinaster) à Pisolithus tinctorius : évaluation de la masse mycélienne et de la mycorhization

To estimate the intensity of mycorrhizal development of maritime pine (Pinus pinaster Soland. in Ait.) associated with Pisolithus tinctorius (Pers.) Coker et Couch., two methods were used: the assay of fungal chitin after acid or alkaline hydrolysis; the measure of absorption of fungus pigments extracted by means of acetone. The products of the hydrolysis of the chitin are assayed by a colorimetric method. The alkaline hydrolysis enables us to directly assay the fungal chitosan; after acid hydrolysis the tissues of pine produce some substances reacting colorimetrically and the absorption due to chitin is estimated from the total absorption of the hydrolysate. There are good correlations between these different types of determination themselves and between the determination and the counting of the mycorrhizae.

Syntheses of permethylated derivatives of pinastric acid and gomphidic acid, pulvinic acid pigments of lichen and fungi

The application of 2-aryl O-methyltetronic acids (7) and (20) to the total synthesis of permethylated derivatives of pulvinic acid pigments found in Lepraria flava and Gomphidius glutinosus is described. Metallation of the tetronic acid (7), followed by treatment with methyl benzoylformate and dehydration of the intermediate carbinol led to O-methyl pinastric acid (9), identical with the O-methyl derivative of natural pinastric acid from L. flava. In a similar manner the tetronic acid (11) and methyl 4-methoxybenzoylformate gave O-methylisopinastric acid (12), and condensation between (20) and methyl 4-methoxybenzoylformate led to permethylated gomphidic acid (21). Comparison of 1H n.m.r. shift data for (21) with those reported for gomphidic acid from G. glutinosus established structure (2b) for the natural metabolite.

Total synthesis of pulvinones, 4-benzylidene-2-phenyltetronic acid pigments of fungi

The application of 2-aryl O-methyltetronic acids (9) and (31) in the total synthesis of pulvinone pigments found in Aspergillus terreus and Suillus grevillei is described. Regioselective reductions of the corresponding maleic anhydride derivatives (8) and (30) with lithium aluminium hydride provide (9) and (31) respectively. Metallation of the tetronic acid (9) using lithium N-cyclohexyl-N-isopropylamide, followed by treatment with p-anisaldehyde and dehydration of the intermediate carbinol led to pulvinone (14). In a similar manner, condensations between (9), and 3,4- and 2,4-dimethoxybenzaldehydes produced pulvinones (17) and (18) respectively. The pulvinone (17) was identical with that obtained from the larch mushroom S. grevillei, but the isomeric pulvinone (18) was not identical with that purported to have this constitution and isolated from A. terreus.Unambiguous syntheses of the prenylated pulvinones (23) and (24) from O-methyltetronic acids (9) and (31) respectively, and the appropriate aryl aldehydes, suggest that the biosynthesis of the bis-chromanated metabolite (22), from (1a)via(20) in A. terreus, proceeds by selective monoprenylation of (1a) leading to intermediate (4a), and by selective chromanation of (20) leading to intermediate (21).

Fungus pigments—XII : The structure and synthesis of thelephoric acid

Degradative and spectroscopical evidence, as well as biogenetic considerations led to the conclusion that thelephoric acid is 2,3,8,9-tetrahydroxybenzobis[1,2-b,4,5-b′]benzofuran-6,12-quinone(VI). This view was confirmed by synthesis, involving condensation of chloranil with two molecules of 3,4-dimethoxyphenol and subsequent demethylation.
