Description Application N-(Benzyloxycarbonyloxy)succinimide (Cbz-OSu) is a common reagent for the carboxybenzyl protection of amines. This reaction is one of the key synthetic steps in the synthesis of: • Enantiomers of cyclic methionine analogs viz, (R)-and (S)-3-aminotetrahydrothiophene- 3-carboxylic acid. • 1′-H-Spiro-(indoline-3,4′-piperidine) and its derivatives. • Total synthesis of (-)-diazonamide A. and (-)-sanglifehrin A. Cbz-OSu is widely employed to protect amino acid residues in peptide synthesis. It can also be used in N-trans diprotection of cyclen regioselectively. Reagent for the selective introduction of the Z-amino protection in amino acids; and in aminoglycoside antibiotics. Packaging 25, 100, 250 g in poly bottle
