摘要

An efficient and versatile protocol to incorporate the achiral and Cα, α-tetrasubstituted 4- amino-1, 2-dithiolane-4-carboxylic acid Adt (1) residue into peptides is described. The 2, 2- bis [(benzylthio) methyl] glycine N-carboxy anhydride (5) was found to be the key reactive intermediate from which both Boc-Adt-OMe (8) and the glutathione analogue H-Glu (-Adt-Gly- OH)-OH (12) can be obtained.
