Synthesis, conformational analysis and SAR research of OSW-1 analogues

A series of novel OSW-1 analogues were synthesized by coupling disaccharides (2-O-4-methoxylbenzoyl-β-D-xylopyranosyl-(1→3)-2-O-acetyl-α-L-arabinopyranosyl) or (2-O-4-(E)-cinnamoyl-β-D-xylopyranosyl-(1→3)-2-O-acetyl-α-L-arabinopyranosyl) and their 1→4 lin

Synthesis of a trisaccharide related to the cytotoxic triterpenoid saponins isolated from the bark of Albizia procera

Chemical synthesis of a trisaccharide related to the cytotoxic triterpenoid saponins isolated from the bark of Albizia procera has been accomplished through a concise stepwise glycosylation strategy starting from commercially available D-xylose, 2-acetamido-2-deoxy-D-glucose and L-arabinose. The target trisaccharide was designed with a 4-methoxyphenyl (MP) aglycone to extend the scope of conversion to suitable glycoconjugates via selective removal of 4-methoxyphenyl (MP) group. An unexpected phenomenon, i.e., the arabinosyl residue assumed the 1C4 conformation instead of the typical 4C1 form, was observed. Deprotection could restore the normal conformation. Copyright
