  Unusual amino acids III. Asymmetric synthesis of 3-arylalanines

  摘要：

  21 (Z)-alpha-N-benzoylamino-beta-arylacrylic acids and their esters were prepared by known procedures and hydrogenated to the corresponding optically active alpha-benzoyl-beta-arylalanine derivatives with optical yields in the range of 82-95% ee using the cationic rhodium complex of ''PROPRAPHOS'' as the chiral catalyst No electronical influences of the substituents at the aryl moiety on the enantioselectivity were observed but a sterical one, proved by X-ray crystallographic analysis and computer-aided modellings. Deacylation of the hydrogenated spezies produced the hydrochlorides of the 3-arylalanines attended by a partial racemisation In this case the hydrogenation of urethane type protected dehydroaminoacid derivatives seems to be the alternative.

  An efficient two‐step synthetic procedure for the preparation of numerous variations of N‐protected α,β‐unsaturated α‐amino acids and their corresponding esters from N‐protected glycine and either aliphatic or aromatic aldehydes was developed. The reaction involved cyclization of the N‐protected glycine into oxazolone, condensation with the aldehyde, and ring opening with a base.
