| Abstract;Arbutin cinnamate was synthesized from arbutin (4-hydroxyphenyl .BETA.-D-glucopyranoside) and vinyl cinnamate by regioselective transesterification with a bacterial lipase (Amano-PS or Novozyme 435) in organic solvent. The product was identified by 1H-, 13C-NMR and FAB-MS analyses. These spectra showed that one ester bond was formed between the primary alcohol moiety of D-glucose of arbutin and the carboxyl residue of cinnamic acid. (author abst.) |
