Microwave-assisted, zinc-mediated peptide coupling of N-benzyl-α,α-disubstituted amino acids
摘要:
Incorporation of the extremely hindered amino acid N-benzylaminoisobutyric acid into dipeptides under microwave irradiation with commercial zinc dust is described. A comparative survey of various methodologies for hindered peptide couplings was undertaken. The optimised coupling conditions were free from racemisation and applicable to other hindered amino acids. (c) 2007 Elsevier Ltd. All rights reserved.
