Amino acid (2-thiosulfatoethyl esters) 4 can be prepared from amino acid (2-chloroethyl esters) by nucleophilic exchange of halogen for thiosulfate.Coupling of the esters 4 with Z-protected amino acids gives the water-soluble Z-dipeptide esters 5 which re
Protease-catalyzed (2+2)-Segment Condensation in an Aqueous-Organic Two-phase System

Tetrapeptides Z-Ala-Phe-X-Ala-NH2 can be prepared in good yields by α-chymotrypsin-catalyzed reactions of Z-Ala-Phe-OMe and X-Ala-NH2 in an aqueous-organic two-phase system using CCl4 as solvent.This method is also advantageous for the synthesis of Boc-Al
