Synthesis of backbone modified cyclic peptides bearing dipicolylamino sidearms
摘要:
Three analogues of the Lissoclinum class of cyclic peptides, bearing dipicolylamino functionalised side chains, have been synthesised using a stepwise approach followed by macrocyclisation. Attempts to incorporate dipicolylamino functionalised side chains prior to peptide synthesis resulted in epimerisation, but this was overcome by functionalising the ornithine side chains with dipicolylamino groups after the macrocyclisation reaction.

modified cyclic peptides, bearing dipicolylamine side chains for metal complexation and subsequent anion binding studies. Two approaches to the cyclic peptides were investigated. Initially, a stepwise approach was employed, involving solid-phase assembly of oxazole-based building blocks, followed by solution-phase macrolactamisation of the resulting linear precursor. The alternativestrategy involved the
