Several related derivatives of salicylic aldehyde, namely A, B, C and D were applied as substrates for the intramolecular [4+2] cycloaddition reaction with anilines under the conditions described above. However, the only product detected in the reaction mixture was the corresponding non-cyclized imine. Attempts to cyclize it under a variety of experimental conditions, including elevated temperatures and various catalysts were not successful. This result may be attributed to the insufficient electron density on the olefinic fragment of A-C, and to the unfavorable thermodynamics for the formation of the [6,7] fused system for D. Similar difficulties in the intramolecular cycloaddition reactions for the formation of [6,7] fused systems have been reported, see for example
