Hl. Holland et al., PREPARATION OF (R)-SULFORAPHANE BY BIOTRANSFORMATION USING HELMINTHOSPORIUM SPECIES NRRL-4671, Tetrahedron : asymmetry, 5(7), 1994, pp. 1129-1130
The fungus Helminthosporium species NRRL 4671 oxidizes 1-isothiocyanat
o-4-(methylthio)butane to (-)-1-isothiocyanato-(4R)-(methylsulfinyl)bu
tane (sulforaphane). Helminthosporium also converts 1-methylthio-4-(N-
phthalimidyl)butane to the (R) sulfoxide.
