The ring opening of epoxides by various amino acid esters is described in refluxing trifluoroethanol without any catalyst. Under these simple conditions the corresponding β-amino alcohols are obtained in good to excellent yields in relatively short reaction times compared to previously reported methods.

In an attempt to produce short-acting beta-adrenergic receptor blockingagents, we prepared several (aryloxy)propanolamines with ester functions incorporated into the nitrogen substituent. Many of these compounds exhibited a short duration of blockingactivity after their continuous intravenous infusion for 40 min. However, their durations were found to increase considerably upon longer intravenous
