✦ Synopsis

Ahset

The title compound (E-1) exhibits a conformational energy preference in which the carbonyl oxygen lies over the aromatic ring. This preferred conformation is shown to exist in the solid state by X-ray analysis of the crystal structure and in the solution phase by COSY studies of the NMR spectrum. Related compounds show no conformational preference in solution at room temperature on
