Processes for the preparation of 3-aminocarboxylic acids and their esters |
摘要 |
The present invention relates to novel processes for the preparation of optically active 3-aminocarboxylic acids and their esters, in particular processes for the preparation of optically active compounds of the formula IA or IB <CHEM> as free bases or as acid addition salts thereof, in which the radicals are as defined in the description; in particular using the catalytic hydrogenation of olefinic precursors in the presence of platinum on alumina as a catalyst and the removal of chiral auxiliary groups from salt precursors; and novel process sections in the route for their synthesis, and processes for the preparation of biologically, in particular pharmacologically, active compounds, which comprise the novel processes.
