The addition of allylic Grignard reagents to R-(-)-carvone and 2-(2-methylpropylidene) cyclohexanone is regio and stereoselective. The stereochemistry assignment of allylcarveols 5-7 and allyl-2-(2-methylpropylidene) cyclohexanols 17-19 is based on infrared and NMR spectral studies.

Keywords : Carvone; Allylcarveols; Organomagnesium; Regioselectivity; Stereoselectivity.
