Fluorinated and iodinated templates for syntheses of β-turn peptidomimetics
摘要:
Various 2-fluoro-5-nitrobenzoic acids and the homocysteine derivative 2 have been combined in solid phase syntheses of the peptidomimetic types 3-6. NMR and CD data collected for some of these compounds indicate that a transannular SO to HN hydrogen bond stabilizes P-turn conformations for the sulfones and one of the sulfoxide epimers. An extensive library of compounds was made and studied to test this assertion. (C) 2002 Elsevier Science Ltd. All rights reserved.
