Replacement of AcO-3 in methyl 2,3-di-O-acetyl-4-O-trityl-β-d-xylopyranoside with a benzyl group greatly increases the 1,2-trans-stereoselectivity of glycosylation with a d-xylopyranose 1,2-O-(1-cyanoethylidene) derivative. Anomerisation of methyl 2-O-benzyl-β-d-xylopyranoside derivatives occurred under the action of triphenylmethylium perchlorate.
