The isolation of 2,4-dihydroxy-3,6-dimethylbenzoic acid (3-methylorsellinic acid) from a culture of Aspergillus terreus
Abstract
3-Methylorsellinic acid (3) was isolated from a culture of Aspergillus terreus; feeding experiment of radio-active precursors showed that formate was incorporated into (3), but not into orsellinic acid (1), suggesting that the methyl carbon at C-3 position was derived from formate.
