Y. Hiraga et al., BIOSYNTHETIC GENERATION OF THE SPECIES-SPECIFIC CHIRALITY OF LIMONENEIN MENTHA-SPICATA AND CITRUS-UNSHIU, Journal of the Chemical Society, Chemical Communications, (17), 1993, pp. 1370-1372
The biosynthetic generation of the species-specific chirality at C-4 o
f (4S)-(-)-and (4R)-(+)-limonenesin Mentha spicata and Citrus unshiu,
respectively, is ascribed to the enantiomeric endo-spatial arrangement
of linalyl cation intermediates which are both formed by the (2Re,3Si
)-face elimination of the diphosphoryl group with respect to the 2(3)-
double bond of geranyl diphosphate.
