Bromelain catalyzed synthesis of peptides in organic solvent

For the first time, immobilized bromelain was shown to maintain high catalytic activity in organic solvent and to form peptide bonds. It requires only 7 hours to obtain Cbz-Gly-L-Leu-OMe in 85% yield. The precursor of aspartame (Cbz-L-Asp-L-Phe-OMe) and other dipeptides were also synthesized by this method.
