of enantiopure masked 1,2-aminoalcohols (ee >99%) including their alkyl substituted analogues has been achieved by the regioselectiveringopening of epoxides using phthalimide, followed by highlyefficientkineticresolution under mild and environmentally friendly conditions. The addition of co-solvents during kineticresolution significantly improved the enantioselectivity with reduction in time
