Websalts with D‑phenylalanine methyl ester 4, the yield of 4 was very low (6.5%). N‑acetyl‑D‑phenylalanine 5 and 1 can generate an insoluble diasteromeric salt with L‑phenylalanine methyl ester 6, which can give good resolution efficiency for 2 in the subsequent steps, However, D‑phenylglycine is less expensive than D‑phenylalanine. The ester methyl α‐phenylglycinate is used to convert carboxylic acids into homologated unsaturated ketones. These reactions proceed via cyclization of phenylglycinamides to oxazolones, which can be reductively cleaved with chromous reagents. from nairobi for example crossword
