4-alkyl-thiophenyl-ethanolamines, having an activity the cerebral circulation, the blood platelet-aggregation and the lipenia

摘要

4-alkyl-thiophenyl-ethanolamines are disclosed, which are compounds having a therapeutical activity against blood-platelet aggregation, and against lipemia and improving the cerebral circulation, said ethanolamines having the general formula: <IMAGE> wherein R and R1 are alkyl substituents and R2 is a substituent having an amine character. Due to the presence of two asymmetry centers in their molecule, the compounds concerned can be prepared in the "threo" and the "erythro" configuration: mixtures of the "threo" and the "erythro" forms have also proven effective.
