M. Schuster et al., CHYMOTRYPSIN-CATALYZED PEPTIDE-SYNTHESIS IN ICE - USE OF UNPROTECTED AMINO-ACIDS AS ACYL ACCEPTORS, Tetrahedron letters, 34(36), 1993, pp. 5701-5702
Kinetically controlled chymotrypsin-catalyzed peptide syntheses are ca
rried out using unprotected amino acids as amino components. The react
ions are performed in frozen aqueous solutions. A gram scale dipeptide
synthesis is described.
