| titleOfInvention |
Process for the preparation of 3-amino-2-oxo-pyrrolidines, novel intermediates and their use |
| abstract |
The present invention relates to a process for the preparation of .gamma.-lactams of the general formula I (see formula I) The invention relates also to novel advantageous intermediates of the general formulae V, IV and II and their salts (see formula V) (see formula IV) (see formula II) and their use. The compounds of the general formula I are obtained by cyclising compounds of the general formula II (see formula II) which can be prepared from the intermediate compounds V. |
