Aryloxy and alkyloxypropanolamines - are obtained in 45 to 70% yields and with 80% of asymmetric induction, using TiCl4induced nucleophilic addition of cyanotrimethylsilane onto chiralacetals derived from racemic 2,4-pentanediol. Therefore, optically pure 2,4-pentanediol will provide, after a purification, optically pure -.
