Series of E-2-benzylideneindanones (a),-tetralones (b) and-benzosuberones (c) with OCH3 (2–4), NO2 (5–7) and F (8–10) substitutions (ortho, meta and para) on their benzylidene moiety were synthesized by aldol condensation of the appropriate aldehydes and benzocyclanones. The stereostructure (configuration and conformation) and the electronic properties (conjugation of the enone moiety with the aromatic rings) of the compounds ...
