Relative and absolute stereochemistry for perforatrin...Relative and absolute stereochemistry for hyperforin has been proposed by Brondz et al. was supported and new isomer of hyperforin-perforatrin has been discovered. Relative and absolute stereochemistry for perforatrin was proposed and elucidated by using gas-chromatography mass-spectrometry with supersonic molecular beams (SMB). The possibility of the existence of ambiguities in chirality as a hypothesis for the existence, and a new understanding, of chiral substances with shifting chirality is presented.展开更多
This short communication is an overview and revision of previous published papers about the relative and absolute stereochemistry of hyperforin and discovery of a new isomer of hyperforin that has been named perforatrin.
