Abstract
N-Acetyl-N-benzyloxy-β-alanine was obtained by Michael addition of N-acetyl-N-benzyloxyamine on terbutylacrylate under solvent-free PTC conditions followed by elimination of the terbutyl group. Polyamines were acylated with N-acetyl-N-benzyloxy-β-alanine. The prepared compounds exhibited a moderate activity against HIV protease.
