Choukchou-Braham, Noureddine,Asakawa, Yoshinori,Lepoittevin, Jean-Pierre

, p. 3949 - 3952 (1994)

New optically active 8-hydroxy-3-alk(en)yl-3,4-dihydroisocoumarins 2a-c were isolated from Ginkgo biloba L. fruits.The absolute configuration was determined to be R by comparison with both enantiomers of the 8-hydroxy-3-tridecyl-3,4-dihydroisocumarin synthesized from optically active epichlorhydrins.
