A series of dipeptide derivatives containing non-coded amino acids, N-Boc-4-X-Phe-Ala-NHNHPh (X = Cl, Br, I, NO2), were synthesized by using thermoase in organic solvents. The physical data were consistent with the same samples prepared by 3-(diethox

3-(Diethoxyphosphoryloxy)-1, 2, 3-benzotriazin-4(3H)-one (DEPBT) was an organophosphorus coupling reagent developed by our group. It was an effective coupling reagent for the synthesis of protected peptides containing Tyr, Ser and Thr with unprotecte

Thioester method for the synthesis of cyclopeptides is improved by using Pac (Pac = phenacyl, CH2COC6H5) ester as a protecting group of 3-mercaptopropionic acid. The Pac group is easy to be removed from C-terminal with zinc in acetic acid. The protec

The activity of enzymes to form a peptide bond in organic solvent was greatly influenced by observed pH and water content. The precursors of two sweeteners, P-Asp-Xaa-OR (P = Z or For, Xaa-OR = Phe-OMe or Ala-OcHex), were synthesized by enzyme, and t

In order to extend the use of proteases to organic synthesis and seek the rules of enzymatic reactions in organic media, we focused on unnatural substrates for proteases to form amide bonds. In this paper, the study of unnatural substrates containing
