Synthesis of cyclic peptides containing nor-lanthionine bridges via a triply-orthogonal protecting group strategy.
8363 - 8366.
We report a new approach to the on-resin synthesis of cyclic peptides containing unnatural thioether side-chain bridges. An orthogonally protected nor-lanthionine was incorporated in a linear precursor peptide via stepwise solid-phase synthesis. This was followed by double allyl deprotection, cyclisation using PyAOP and subsequent chain-cxtension to give an analogue of ring C of nisin. (C) 2002 Elsevier Science Ltd. All rights reserved.
