| titleOfInvention | Process for inverting the configuration of optically active compounds, and optically active intermediates produced in this process |
| abstract | ABSTRACT OF THE INVENTION The invention relates to a process for inverting the configuration at the optically active carbon atom (*) in compounds of the formula I (I) in which A denotes a carbocyclic or heterocyclic aromatic radical and R denotes an aliphatic, cycloaliphatic or araliphatic hydrocarbon radical, by formylation, treating the resulting compounds with a strong acid or an acid halide and cleaving the oxazolinium derivatives thus obtained, by acid or alkaline hydrolysis, if appropriate via the stage of the N-formyl compound, and to oxazolinium derivatives of the formula III (III) in which A and R have the meanings defined above and in which X? represents the anion of a strong acid or of a halogen atom and formed as intermediate products. Compounds of the formula IV (IV) in which A and R have the meanings defined above, possessing the same structure as the starting material I but having an opposite configuration at the carbon atom (*), can be used as .beta.-blocking agents. |
