(-)-(S)-Sedanenolide - Celery stem odor, strong, fresh, with aspects reminiscent of celery fibers. Odor threshold = 0.14 ppm = (-)-(S)-3-butyl-4,5-dihydroisobenzofuran-1(3H)-one or (-)-(S)-3-butyl-4,5-dihydro-2-benzofuran-1(3H)-one Ref: D. Oguro & H. Watanabe, Asymmetric Synthesis and Sensory Evaluation of Sedanenolide, Biosci. Biotechnol. Biochem., 75 (8), 1502-1505 (2011)
