| Enantioselective synthesis starting form (E)-2-hexenol showed that (+)- and (-)-(Z)-2-methyl-4-propyl-1,3-oxathiane exhibit different organoleptic properties. Whereas the (+)-enantiomer had a estery-camphoraceous-flowery type odor, (-)-(Z)-2-methyl-4-propyl-1,3-oxathiane smelled powerful sulfury, tropical-fruit-like (th 4ppm). \\ | Enantioselective synthesis starting form (E)-2-hexenol showed that (+)- and (-)-(Z)-2-methyl-4-propyl-1,3-oxathiane exhibit different organoleptic properties.
