Preparation of regioselectively feruloylated p-nitrophenyl alpha-L-arabinofuranosides and beta-D-xylopyranosides-convenient substrates for study of feruloyl esterase specificity.


p-Nitrophenyl alpha-L-arabinofuranoside and beta-D-xylopyranoside mono-O-ferulates were prepared by 4-O-acetylferuloylation of corresponding enzymatically prepared di-O-acetates followed by deacetylation. An alternative mild acylation catalysed by zinc oxide was tested on xylopyranoside derivatives. The chemoselective methanolysis of the acetyl groups using… (More)
