Abstract:The presence of planar chirality of a variety of medium-sized heterocycles, along with nine-membered cyclic ketone and its enol ester, was revealed by observation of isolable enantiomers by analytical high-performance liquid chromatography (HPLC) using a chiral stationary phase with a polysaccharide-based chiral selector. Several tens of milligrams of enantiomers of the planar-chiral molecules were successfully separated by preparative-scale HPLC, leading to the preparation of an enantioenriched sample.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
