CONNECTION FOR USE AS A CATALYSATOR FOR ASYSTERICAL HYDROGRAPHS OF ALFA-ACYLAMINOACRYLS AND/OR SALTS THEREOF

摘要

Asymetric hydrogenation of beta-substd.-alpha-acylamidoacrylic acrds or their salts is carried out in the presence of a co-ordination complex of rhodium, iridium, ruthenium, osmium, palladium or platinium with at least one optically active phosphine or arsine cpd. The reaction may be used for producing L-DOPA, an anti-parkinson agent.
