Practical preparation of Z-α-(N-acetylamino)- and Z-α-(N-benzoylamino)-α,β-unsaturated acids

Jursic, Branko S.,Sagiraju, Sarada,Ancalade, Dustin K.,Clark, Traneil,Stevens, Edwin D.

, p. 1709 - 1714 (2008/02/01)

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. Copyright Taylor & Francis Group, LLC.
