The absolute configuration of ( )-3-hydroxy-a-calacorene
3-Hydroxy-a-calacorene was identified in extracts from cold-shocked seedlings of cotton (Gossypium hirsutum L.) and kenaf (Hibiscus cannabinus L.), both of which are members of the Malvaceae family. ( )-3-Hydroxy-a-calacorene was isolated from Heterotheca inuloides Cass. (Asteraceae). HPLC on a chiral stationary phase column showed that the 3-hydroxy-acalacorene from cotton and kenaf had the sa...

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 ...
متن کاملAbsolute configuration of micromelin
The title compound {systematic name: 7-meth-oxy-6-[(1R,2R,5R)-5-methyl-4-oxo-3,6-dioxabicyclo-[3.1.0]hexan-2-yl]-2H-chromen-2-one}, C(15)H(12)O(6), is a coumarin, which was isolated from the roots of Micromelum glanduliferum. There are two mol-ecules in the asymmetric unit with slight differences in bond angles. In both mol-ecules, the furan ring adopts a flattened envelope conformation. In the...
