pyrrole-based amino acids have been prepared through the microwave assisted Paal–Knorr reaction of 1–4 ketoesters derived from the corresponding β-ketoester with a functional homologation. The carboxylic group is located in position 3 of the pyrrole, whereas the amino group, protected with the Cbz moiety, is present on the side chain in positions 1 or 2. These compounds were used to prepare constrained oligopeptides

The biologically important amino acid statine, (3S,4S)-4-amino-3-hydroxy-6-methylheptanoic acid, as well as optically active statineanalogues, are readily accessible in the ester form by simple reduction of the corresponding N,N-dibenzyl β-keto esters using NaBH4 followed by deprotection.
