A series of chiralβ-aminoalcohols was prepared by the reaction of secondary amines with a 1:1 mixture of cis- and trans-limonene oxide in the presence of water as a catalyst. The β-aminoalcohol obtained was derived from the trans-limonene oxide, and the unreacted cis-limonene oxide was recovered from the reaction mixture. The β-aminoalcohols are useful chiralauxiliaries for the addition of diethylzinc
