Abstract: A series of model compds. representing the hypothetical β-ether type linkage between lignin and hemicellulose were synthesized by phenacylation of Me β-D-xylopyranoside diacetate with methoxydiazoacetophenone derivs. in the presence of BF₃.Et₂O. The formed phenacylxylopyranosides, such as Me 2-O-(3,4-dimethoxyphenacyl)-β-D-xylopyranoside 3,4-diacetate, etc., were isolated by chromatog. The target products, such as Me 2-O-[2-hydroxy-2-(3,4-dimethoxyphenyl)ethyl]-β-D-xylopyranoside , etc., were obtained by subsequent deacetylation and redn.
