(-)-(S)-Undecavertol (ee = 75%) - Weaker enantiomer, fruity-green, pinefir balsam note with aspects of tea, not so typical of Undecavertol. Odour threshold: 4.7 ng/L air. = (3E,5S)-4-methyldec-3-en-5-ol Ref: Agnese Abate, Elisabetta Brenna and Ginevra Fregosi, Bio-catalysed synthesis of optically active Undecavertol enantiomers, Tetrahedron: Asymmetry 16 (2005) 1997–1999

(+)-(R)-Undecavertol (ee = 93%) - Typical Undecavertol odour, floral, green, fresh, violet leaves, stronger and greener than the racemic commercial material, with aspects of cucumber and Neofolione (methyl non-2-enoate). Odour threshold: 0.31 ng/L air. = (3E,5R)-4-methyldec-3-en-5-ol Ref: Agnese Abate, Elisabetta Brenna and Ginevra Fregosi, Bio-catalysed synthesis of optically active Undecavertol enantiomers, Tetrahedron: Asymmetry 16 (2005) 1997–1999
