Synthesis of Phenylalanine-based Cyclic Acylated Enamino Ester Dipeptide Analogues: Inhibitors of α-Chymotrypsin. X-Ray Molecular Structure of (2'S,4'R)-4'-Benzyl-3'-benzyloxycarbonyl-5'-oxo-2'-phenyloxazolidin-4'-ylacetic Acid

Alkylation of the (S)-phenylalanine-derived syn-oxazolidinone 8 with BrCH2CO2CHPh2 gave compound 9, a key precursor to the β-keto ester 11 and the keto acid phosphorane 17.Compound 17 gave the enolactone 24 on heating and the bromo enolactone 19 and 20 on
