Reaction Steps

When it is subjected to methanolysis (i.e., heated under reflux in 9% hydrochloric acid-dry methanol), it gives 1 mol each of methylgalactoside, methylarabinoside and methylglucuronide, and 2 mols of methylglucoside. A completely methylated compound (C77H132O29) obtained by methylation of soyasaponin A1 with methyl iodide, dimethyl sulfoxide and sodium hydride gives 1 mol each of methyl 3,4-di-O -methylglucopyranoside, methyl 3,4,6-tri-O -methylgalactopyranoside and methyl 2,4-di-O-methylarabinopyranoside, and 2 mols of methyl 2,3,4,6-tetra-O-methylglucopyranoside when subjected to methanolysis after reduction. It also gives 1 mol of 3,22,24-tri-O-methyl soyasapogenol A (C33H56O4).
