(3S,3aS,7aR)-3-Butylhexahydrophthalide - sweet and sickly Also known as: (3S,3aS,7aR)-3-butylhexahydro-2-benzofuran-1(3H)-one It should be noted that we only show two of the eight 3-butylhexahydrophthalide stereoisomers. Of the two isomers shown here, only the odorless 3R,3aR,7aS isomer is found in celery, celeriac, and fennel. Ref: Bartschat, D.; Wust, M.; Hanssum, H.; Mosandl, A.
