Summary
-
1.
By the condensation of acetobromoglucose with methyl oleanolate in presence of mercuric acetate and with 3-O-acetyloleanolic acid in presence of silver carbonate methyl oleanolate α-D-glucoside and 1-(3-O-acetyl-oleanoloyl)-β-D-glucopyranose were obtained, respectively.
-
2.
By the halolysis of methyl oleanolate α- andβ -glucosides with lithium iodide in collidine, oleanolic acid 3-O-α- and 3-O-β -glucosides were obtained, respectively, which indicates the stability of a glycoside link of the usual type under the conditions of the halolysis reaction.
-
3.
With 1-(3-O-acetyloleanoloyl)-β -D-glucose and araloside A as examples, the possibility of the selective cleavage of the acyl glycoside link in halolysis was demonstrated.
