Summary: | (S)-alpha-ethyl-2-oxo-1-pyrrolidineacetamide, its preparation and pharmaceutical compositions containing the same. It can be prepared either by reacting (S)-alpha-ethyl-2-oxo-1-pyrrolidineacetic acid successively with an alkyl haloformate and with ammonia, or, by cyclizing an (S)-2-amino-butanamide of the formula X-CH2CH2-NHCH (C2H5)CONH2 wherein Y is a -CH2-radical when X represents a ZOOC-radical and Y is a -CO- radical when X represents a HalCH2-radical, Z being a C1-C4 alkyl radical and Hal a halogen atom. This laevorotatory enantiomer has been found to have significantly higher protective activity against hypoxia and ischemia than the corresponding racemate. |
