Asymmetric Synthesis of (-)-Muricatacin’s Analogue (4S,5R)-5-Hydroxy-4-octadecanolide Exhibiting the Cytotoxicity against Esphageal Cancer Cells
摘要:
An efficient and facile synthesis, in six steps and 50% overall yield from commercial D-(-)-lyxose as starting material via twice Wittig olefination and one-pot deisopropylidenation and intramolecular lactonization, of the enantiopure (4S,5R)-(+)-5-hydroxy-4-octadecanolide (2), analogue of (-)-muricatacin, and the cytotoxic activity against CE48T cell line (human esophageal carcinoma) are described and the biological activity is the first shown in the literature.
