Pseudoaxially disubstituted cyclo-β3-tetrapeptide scaffolds

Sutton, Peter W.,Bradley, Adrian,Farràs, Jaume,Romea, Pedro,Urpí, Fèlix,Vilarrasa, Jaume

, p. 7947 - 7958 (2007/10/03)

An N,N-disubstituted cyclo-β3-tetrapeptide, identified as a potential molecular scaffold, has been synthesised on a multigram scale from β-homophenylalanine by employing a nosylate-based protection strategy. C2-Symmetric derivatives containing pseudoaxial, combinatorially addressable functionalities have been prepared from the parent cyclopeptide. (C) 2000 Elsevier Science Ltd.
