Abstract Treatment of convolvulin (the ether insoluble portion of purified jalap resin) with sodium methoxide in methanol has yielded a new β- d -quinovoside. Periodate oxidation and methylation studies together with chemical and spectroscopic analyses have shown this fragment to consist of one molecule of d -quinovose glycosidically linked to a molecule of methyl 11-hydroxytetradecanoate.

ropyran iodide are elaborated from D-glucose each in practicable procedures of 5 and 10 steps, resp., and subsequently joined to give, after oxidation, deprotection and acetylation, (−)-anamarine (ent-). The synthesis proves the absolute configuration of natural (+)-anamarine ().
