Four-dimensional orthogonal solid-phase synthesis of new scaffolds based on cyclic tetra-β-peptides
摘要:
A four-dimensional orthogonal protecting scheme that involves the acid-labile BAL linker in conjunction with Fmoc, Alloc and pNb protecting groups. which can be removed by P-elimination. allyl transfer. and reductive hydrolysis, respectively. allows the solid-phase preparation of scaffolds based on a cyclic tetra-p-peptide with free amino side chains beady for further elaboration.
