  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-dihydroisocoumarin synthesized from optically active epichlorhydrins.
