| Zusammenfassung: | Methyldihydrousnic acid was obtained by methylation of dihydrousnic acid and itsconstitution was elucidated as (I). The result that 3'-methyl-2', 6'-dihydroxyacetophenone was obtained from methyldihydrousnic acid indicates that the resorcinol type of compound is derived from B-ring of (I). This result also presents the experimental proof of formation of 3'-methyl-2', 6'-dihydroxyacetophenone, one of resorcinol type of compound, from B-ring of dihydrousnic acid. |
