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 R1 is CHEM and R2 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.
