Application of synthetic acyl glucopyranosides for white-rot and brown-rot fungal decay resistance in aspen and pine wood

Due to its non-toxicity and environmentally friendly nature, carbohydrate-based fatty acid (CFA) esters are encouragingly used as antimicrobials synthetic intermediates. They also notably applied in food, surfactant, pharmaceutical industries. In this respect, methyl 2,6-di-O-isopentanoyl-α-D-glucopyranoside (2), synthesized a single step from α-D-glucopyranoside (1), was converted into four other 3,4-di-O-acyl (3 – 6). All the newly CFA (2 6) were for first time study decay resistances of aspen (Populus tremula) pine (Pinus sibirica) wood caused by white-rot (Polyporous versicolor L.ex. Fr.) brown-rot (Postia placenta (Fr). Cke.) fungi. Most these protected woods fungal attack, reduced deterioration, preserved weight percentage at certain point. It is noted that compounds deterioration suppressed loss point low moderate against selected
