The synthesis of all eight configurational isomers of acyclic 1,2,3,4,6-pentols belonging to the 2R enantiomeric series is described. The 1-anthroyl-2,3,4,6-p-methoxycinnamates of these pentols give rise to unique excitoncoupledcirculardichroicspectra in the range of 220–380 nm. Comparisons with the CD of corresponding bichromophoric derivatives of the lower homologous tetrols, 1-anthroyl-2,3,

Reference CD curves (measured in methylcyclohexane) of a homologous series of 1,2-polyols up to pentols derivatized as anthroates at 1-OH and p-methoxycinnamates at the remaining hydroxyl groups show a systematic trend that greatly simplifies assignments of relative and absolute configurations. The same trend also holds for the corresponding 1-aminopolyols, but not for 2-aminopolyols.
