Absolute Configuration of (+)--Dihydrotetrabenazine, an Active Metabolite of Tetrabenazine
Chiral column liquid chromatography and enantiospecific enzymatic hydrolysis were utilized to separate the enantiomers of aand b-dihydrotetrabenazine and a-9-O-desmethyldihydrotetrabenazine, three benzo[a]quinolizines derived from the amine-depleting drug tetrabenazine. An X-ray crystal structure analysis of (−)-a-9-Odesmethyldihydrotetrabenazine gave an absolute structure of that compound as t...
متن کاملAbsolute configuration of a metabolite in the m-fission pathway of protocatechuate.
An aldolase, which is induced in Pseudomonas testosteroni during growth with p-hydroxybenzoate, preferentially attacks the R form of 4-hydroxy-4-methyl-2-oxoglutarate, a metabolite of protocatechuate catabolism.

The title compound, C(33)H(42)O(5), known as xerophenone A {systematic name: (1R,3R,4R,6S,8E,10R)-10-hy-droxy-8-[hy-droxy(phen-yl)methyl-ene]-4-methyl-1,6-bis-(3-methyl-but-2-en-1-yl)-3-(3-methyl-but-3-en-1-yl)-11-oxatricyclo-[4.3.1.1(4,10)]undecane-7,9-dione} is a naturally occurring rearranged benzophenone compound which was isolated from the twigs of Garcinia propinqua. The absolute configur...
متن کاملAbsolute structure and absolute configuration.
Fundamental notions concerning absolute structure and absolute configuration, and their determination from single-crystal diffraction measurements, are presented and reviewed. A glossary of terms with definitions useful in this field is provided. For absolute structure and its determination, the separate but interacting influences of the structure and the inversion-distinguishing power of an X-...
متن کاملAbsolute configuration of isoeichlerialactone
The title seco-dammarane triterpenoid, C(27)H(42)O(4) (systematic name: 3-{(3S,3aR,5aR,6S,7S,9aR,9bR)-6,9a,9b-trimethyl-3-[(R)-2-methyl-5-oxotetra-hydro-furan-2-yl]-7-(prop-1-en-2-yl)dodeca-hydro-1H-cyclo-penta-[a]naphthalen-6-yl}propanoic acid), has been isolated for the first time from the seeds of Aglaia forbesii. The mol-ecule has three fused rings and all rings are in trans-fused. The two ...
