| titleOfInvention | Process for the preparation of optically unitary 2-azetidinone derivatives |
| abstract | 1. A process for the manufacture of optically uniform beta -lactams of the general formula see diagramm : EP0116854,P10,F1 wherein R**1 signifies lower alkanoyl, lower alkoxycarbonyl or benzoyl, R**2 signifies hydrogen, lower alkyl, lower alkanoyl, lower alkoxycarbonyl or cyano, R**3 signifies hydrogen or lower alkyl, B signifies lower alkylidene, lower cycloalkylidene or carbonyl and Z signifies lower 2-alkenyl or 2,4-di(lower alkoxy)benzyl, whereby the residues denoted as lower have a maximum of 7 carbon atoms, and their corresponding optical antipodes, characterized by reacting a salt of a carboxylic acid of the general formula see diagramm : EP0116854,P10,F2 wherein R**1, R**3 have the above significance, in the presence of a reactive derivative of an organic sulphonic acid and a base with an optically uniform compound of the general formula see diagramm : EP0116854,P11,F3 wherein B and Z have the above significance, or the optical antipode thereof. |
