(+)-(2R,3S)-2,3-Methano-1-pentanol - Difusive ether green odor, close to nor-leaf alcohol, more green than the racemate or its enantiomer The racemate is described as Acidic ether fruity odor, less green than nor-leaf alcohol (cis-2-penten-1-ol). = (+)-((1R,2S)-2-ethylcyclopropyl)methanol Ref: Hiroki Asao, Hiroyuki Sakauchi, Shigefumi Kuwahara and Hiromasa Kiyota, Synthesis and odor description of optically active cyclopropanated analogues of geraniol, nerol, nor-leaf alcohol, and matsutake alcohol, Tetrahedron: Asymmetry, 18 (2007) 537–541

(-)-(2S,3R)-2,3-Methano-1-pentanol - Weak rosy odor without characteristic green aspect found in the racemate The racemate is described as Acidic ether fruity odor, less green than nor-leaf alcohol (cis-2-penten-1-ol). = (-)-((1S,2R)-2-ethylcyclopropyl)methanol Ref: Hiroki Asao, Hiroyuki Sakauchi, Shigefumi Kuwahara and Hiromasa Kiyota, Synthesis and odor description of optically active cyclopropanated analogues of geraniol, nerol, nor-leaf alcohol, and matsutake alcohol, Tetrahedron: Asymmetry, 18 (2007) 537–541
