520 3 _aThe isolation of herqueichrysin from Penicilhum herqueiand its conversion into atrovenetin (1 b)are described. The structure of dernethylherqueichrysin (3a)(8,9-dihydro-2,3,4,7-tetrahydroxy-6,8,8,9-tetramethylphenaleno[1.2-blfuran-I -one)ts established by synthesisfrom 9-hydroxy-6.7.8-trimethoxy-4-methyl-3- (3-methylbut-2-enyloxy)- phenalen-I -one ( 6 ) . The isolation of partially racemised atrovenetin (1 b)and deoxyherqueinone (la)from P. herquei is also described.
