Absolute Stereochemistry of Tanabalin, an Insect Antifeedant Clerodane fromTanacetum balsamita
摘要:
The absolute structure of tanabalin (= 12S-acetoxyhautriwaic acid), an insect antifeedant isolated from Tanacetum balsamita, was determined by X-ray crystallography together with modified Mosher’s method, in which an anomalous Δδ value of a proton was verified with an l-adrenaline derivative as a model compound.
