A new, mild two-step synthesis of racemic β-amino acids starting from 2-alkyl-Δ2-oxazolines is described. The process implies the initial formation of masked N-substituted or N-unsubstituted β-enamino acid derivatives followed by chemoselective reduction of the enamino moiety. The process takes place with high yields, total chemoselectivity and moderate diastereoselectivity.

A new method of synthesis of racemic β-amino acids 6 by reduction of masked N-substituted and N-unsubstituted β-enamino acid derivatives 4 via C- protected β-amino acids 5 is described. The process occurs with high yields, total chemoselectivity and moderate diastereoselectivity. Readily available starting materials, inexpensive reagents and mild conditions are used to furnish derivatives 5 and 6.

A simple and efficient route to masked β-amino-α,β-unsaturated acids 3 by reaction of metalated oxa- and thiazolines with nitriles has been developed. The reactivity of 3 has also been explored.
