Reaction Conditions:

Stage #1:L-lysine with L-serin;L-leucine;β‐cyclodextrin in aq. buffer; pH=8 at 20; for 0.0833333 h;
Stage #2:benzyl chloroformate in aq. buffer at 20;chemoselective reaction;Reagent/catalyst;

Steps:

General procedure: β-Cyclodextrin (0.1 mmol) was dissolved in 0.1 M carbonate buffer (pH = 8)(10 mL) at room temperature, the L-lysine (1 mmol) and other amino acids (1 mmol)were added, and the reaction mixture was stirred for 5 min. Cbz-Cl (1 mmol) wasadded and stirring was continued at room temperature until the reaction was complete.The reaction mixture was extracted with ethyl acetate (2 × 5 ml). The solvent wasremoved under vacuum and the products were obtained.
