An N,N-disubstituted cyclo-beta(3)-tetrapeptide, identified as a potential molecular scaffold, has been synthesised on a multigram scale from beta-homophenylalanine by employing a nosylate-based protection strategy. C-2-Symmetric derivatives containing pseudoaxial, combinatorially addressable functionalities have been prepared from the parent cyclopeptide. (C) 2000 Elsevier Science Ltd. All rights reserved.
Design and synthesis of a novel cyclo-β-tetrapeptide
摘要:
N-Substituted tetralactams (cyclo-beta-tetrapeptides) have been identified as potential molecular scaffolds by computer-aided design; compound 2, arising from L-beta-homophenylalanine, has been prepared as a model system and its structure elucidated by single crystal X-ray analysis and NMR spectroscopy.
