摘要

Carbamate Derivatives of 4-Amino-3-isoxazolidinones, 3-Amino-1-hydroxypyrrolidin-2-ones and 1-Amino-1-cyclopropanecarboxylic acid analogs, a process for their preparation and their use as medicaments <CHEM> where R<5> is <CHEM> and R<6> is <CHEM> and to a process for their preparation. The compounds are useful for alleviating various memory dysfunctions characterized by a cholinergic deficit such as Alzheimer's disease.
