Abstract: In hydrocarboxylating an alpha-enamide with CO and an organic hydroxyl cpd. to produce an N-acyl-alpha-amino acid ester whose alpha C atom is chiral, the improvement comprises using as the organic hydroxyl cpd. reactant an organic hydroxyl cpd. which also has a chiral C atom that is all L or D, thereby producing a reaction mixt. having no enantiomeric pairs and contg. diastereomeric N-acyl-alpha-amino acid esters having 2 chiral centres, the hydrocarboxylating simultaneously creating (1) the ester, the chirality of the alpha C atom in L, D furn and (2) the second chiral centre in the ester in all L or all D form.

Abstract: Disclosed is a process for making ethylamines by the hydrogenation in a reaction zone of acetonitrile contained in a basic aqueous solution which also contains HCN, which comprises continuously passing hydrogen gas in contact with a flowing steam containing acetonitrile, water and HCN, which stream is in contact with a solid hydrogenation catalyst, wherein the hydrogen contact time is in the range from 0.5 seconds to 20 minutes and the molar ratio of H2 to acetonitrile charged to said reaction zone is in the range 2-200:1.
