Conclusions
-
1.
4-O-(p-Tolyldiphenylmethyl)-, 4-O-(di-p-tolylphenylmethyl) and 4-O-(p-anisyldiphenyl-raethyl) derivatives of methyl-2,3,-di-O-acetyl-β-D-xylopyranoside were synthesized.
-
2.
A study of the reaction of the above compounds with 3,4-di-O-acetyl-1,2-O-[1-(endo-cyano)ethylidene]-α-D-xylopyranose showed that exchange of the trityl group in methyl-2,3-di-O-acetyl-4-O-trityl-β-D-xylopyranoside for triarylmethyl groups containing electron-donor substituents in the aromatic ring does not appreciably affect the stereochemistry of the glycosylation, but can lead to decrease in the yield of the disaccharides.
-
3.
A trans-triarylmethylation reaction was discovered with the reaction of methyl-2,3-di-O-acetyl-4-O-(p-anisyldiphenylmethyl)-β-D-xylopyranoside with triphenylmethylium perchlorate as an example.
