Synthesis and CD spectroscopy of polyethers with homochiral and heterochiral layers of stereocentres
摘要:
Eight polyethers with three to nine stereocentres have been synthesised using chiral base methodology. Examination of the polyethers by CD spectroscopy revealed clear differences between homochiral isomers and isorners with a heterochiral relationship between an 'inner' layer of stereocentres and an outer' layer of stereocentres. A hypothesis to account for these differences has been advanced. (C) 2008 Elsevier Ltd. All rights reserved.
