New Way for the Preparation of 4-Phenyl-2-oxobutyric Acid Ethyl Ester
New way for the preparation of 4-phenyl-2-oxobutyric acid ethyl ester 1 has been elaborated. The four-steps synthesis from ethyl pyruvate involves the consecutive condensation of ethyl pyruvate with benzaldehyde, hydrogenation of benzylidenepyruvic acid sodium salt 2a to 4-phenyl-2-hydroxybutyric ac...

| Zusammenfassung: | New way for the preparation of 4-phenyl-2-oxobutyric acid ethyl ester 1 has been elaborated. The four-steps synthesis from ethyl pyruvate involves the consecutive condensation of ethyl pyruvate with benzaldehyde, hydrogenation of benzylidenepyruvic acid sodium salt 2a to 4-phenyl-2-hydroxybutyric acid 3 on Ni catalysts, esterification of 3 and oxidation of the ester to 1 with CrO
