- SYNTHESIS OF (-)-DIHYDROMAHUBANOLIDE B AND (-)-ISODIHYDROMAHUBANOLIDE B
-
The total synthesis of (-)-dihydromahubanolide B and (-)-isodihydromahubanolide B isolated from the Amazonian Lauraceae Licaria mahuba (Samp.) Kosterm was achieved starting from (-)-methyl 5-hydroxymethyl-2,2-dimethyl-1,3-dioxolane-4-carboxylate which was readily available from L-(+)-tartaric acid.
