A compound having the general formula ##STR1## in which R represents a hydrogen atom or a hydroxyl radical, R.sub.1 represents a hydrogen atom or a methyl radical, and R.sub.2 represents a phenylethyl radical, a C.sub.1 -C.sub.16 alkyl radical, or a C.sub.6 -C.sub.16 monocyclic, polycyclic or alicyclic radical optionally bonded through a methylene radical, and its pharmaceutically acceptable acid addition salts, the formula (I) having the L-configuration when R is OH and when R and R.sub.1 are both hydrogen, and having the DL-configuration when R is hydrogen and R.sub.1 is methyl. These compounds and salts are useful as medicaments in human and veterinary medicine for cardiovascular and/or neurological treatment.

reactions of alcohols with acetic, chloroacetic, trifluoroacetic, propionic, stearic, and benzoic acids were catalyzed with Ce(OTf)4 in a solvent or under solvent-free conditions with high yields. The formylation and acetylation of primary and secondary alcohols were also easily achieved in ethyl formate and ethyl acetate. A high retention of the configuration was observed in the acetylation and formylation
