New access to racemic β3-amino acids

A general simple procedure having the potential for large scale preparations of racemic β3-amino acids has been developed. The procedure involves base-catalyzed Michael-type addition of sodium diethyl malonate to N-Boc-α-amidoalkyl-p-tolyl sulfones in tetrahydrofuran. Hydrolysis of the adducts by refluxing with 6 M aqueous hydrochloric acid affords β3-amino acid hydrochlorides in high yield and excellent purity.

Tripeptides having a 3-bromobenzyl group at the C-termini and an acryloyl group at the N termini undergo efficient intramolecular Heck reactions to afford the corresponding cyclic peptides in good yields. Synthesis of two such peptides is discussed.
