Total synthesis of a stereoisomer of bistramide C and assignment of configuration of the natural product.

After the isolation of the bioactive polyether bistramide C from the marine ascidian Lissoclinum bistratum in 1988, NMR spectroscopic investigations over the next 12 years reduced the total number of possible stereoisomers of this compound from 1024 to 32. Based on the preparation of segments of the natural product as well as the total synthesis of a randomly selected stereoisomer of bistramide...

Solution-state conformations of natural products from chiroptical spectroscopy: the case of isocorilagin.

Isocorilagin, the α-anomer of the ellagitannin corilagin, has been frequently reported in the literature as a constituent of various plant species. Its identification is based mainly on the smaller value for the coupling constant of its anomeric proton when compared to that of corilagin. A careful investigation of the corilagin structure in both methanol and DMSO solutions using NMR, electronic...
