Two new dihydroisocoumarins from the fungus Cephalosporium sp. AL031.
Two new dihydroisocoumarins, 3,4-dihydro-3-heptantrienyl-8-hydroxyl-6-hydroxymethyl-5-methylisocoumarin and 6-acetoxymethylene-3,4-dihydro-3-heptantrienyl-8-hydroxyl-5-methylisocoumarin were isolated from a culture broth of a strain of the fungus, Cephalosporium sp. AL031. Their structures were elucidated by interpretation of their spectroscopic data.
