| titleOfInvention | Process for the separation of optical isomers from 1,4-dihydropyridine derivatives |
| abstract | New process for separating optical isomers of the compounds of general formula I: <IMAGE> in which: - Ar denotes a phenyl radical optionally containing one to five identical or different substituents, each denoting a halogen atom, an alkoxy radical containing from 1 to 4 carbon atoms, an alkylthio radical containing from 1 to 4 carbon atoms, a trihalomethyl radical or a methylenedioxy radical, - each of Y, Z, Y1 and Z1, which are identical or different, denotes a hydrogen atom, a linear or branched lower alkyl radical containing from 1 to 4 carbon atoms, a cyclopropyl radical, a dicyclopropylmethyl radical, a 2,2-dicyclopropylethyl radical, a 2,2-dicyclopropylethylene radical, a 3,3-dicyclopropylpropyl radical, a 3,3-dicyclopropyl-1-propylene radical, a linear or branched alkylene radical containing from 2 to 5 carbon atoms or a phenyl radical optionally substituted by a nitro radical, and - n is equal to 1, 2 or 3. |
