Genomic characterization and fermentation study of the endophyte Stemphylium sp. (Aa22), a producer of bioactive alkyl-resorcinols. [PDF]

open access: yesPLoS ONE
The genome of the previously described endophytic fungus Stemphylium sp. (strain Aa22) has been sequenced to near completion. Phylogenomic analysis placed strain Aa22 in close proximity to Stemphylium lycopersici. Strain Aa22 had been previously reported

From Maleic Anhydrides to Substituted Resorcinols

open access: yesCHIMIA, 2000
Symmetrically substituted maleic anhydrides react at ?78 °C with lithiomethyl phenyl sulfone to give the corresponding 4-hydroxy-4-(phenylsulfonylmethyl)-buteno-4-lactones, which, on treatment with Mel/K2C03 in acetone, are transformed into 5 ...

Alkylresorcinols in rye (Secale cereale L.) grains. VI. Colorimetric micromethod for the determination of alkylresorcinols with the use of diazonium salt, Fast Blue B

open access: yesActa Societatis Botanicorum Poloniae, 2014
A simple and precise method for alkylresorcinols determination was elaborated. The method a based on coupling of alkylresorcinals with diazotized Fast Blue B, in acidified propaaiol. The method is highly specific for 5-n-alkyl derivatives of resorcinols.
