Abstract:
A series of anthracenecarboxylate(AC)-appended 2,3-di-O-methylcelluloses (AC-Cells) of varying degrees of substitution (DS) were synthesized to examine their photochirogenic behavior under a variety of conditions. The product distribution and enantiomeric excess of the cyclodimers obtained upon photoirradiation and the subsequent saponification were critical functions of the DS and conversion, for which a conformational change of the flexible polymer backbone is likely to be responsible.
