Quantitative Analyses of the Four Isomers of 3,4-Diphenylcyclopentene by Chiral Gas Chromatography

Article abstract of DOI:10.1021/jo00123a010

The four isomers of 3,4-diphenylcyclopentene are well resolved by chiral gas chromatography on a Cyclodex B column, eluting in the ordered sequence (3S,4R), (3R,4S), (3S,4S) and (3R,4R).Absolute stereochemical assignments were made through chemical correlations relating the 3,4-diphenylcyclopentenes with a known reference compound, (1S,2S)-(+)-cis-2-phenylcyclopentanol.
