Abstract

A pair of atropisomers due to restricted rotation about Dsp3-Csp2 bond for 1-(4’-nitrobenzoyl)-2-(2"-hydroxynaphthyl)-3,3-dimethylindoline was isolated. The crystal structures of a pairs of the atropisomers indicate the presence of a significant through-space interaction between the aryl moieties.
