Abstract
The isolation of herqueichrysin from Penicillium herquei and its conversion into atrovenetin (1b) are described. The structure of demethylherqueichrysin (3a)(8,9-dihydro-2,3,4,7-tetrahydroxy-6,8,8,9-tetramethylphenaleno[1,2-b]furan-1-one) is established by synthesis from 9-hydroxy-6,7,8-trimethoxy-4-methyl-3-(3-methylbut-2-enyloxy)-phenalen-1-one (6). The isolation of partially racemised atrovenetin (1b) and deoxyherqueinone (1a) from P. herquei is also described.This publication has 1 reference indexed in Scilit:
