Özet

In this work, the inverse-electron demanded Diels-Alder cycloaddition reaction of 1-dimethylaminomethyl-2-naphthol and 2-dimethylaminomethyl-4,5-dimethylphenol with (un)substituted styrenes were investigated. 3,4-Dihydro 2-(un)substitutedphenyl-2H-benzo[f]chromenes and 2-(un)substitutedphenyl-6,7-dimethylchromans were isolated from the reaction of 1-dimethylaminomethyl-2-naphthol and 2-dimethylaminomethyl-4,5-dimethylphenol with (un)substituted styrenes. The yields of the Mannich bases and the reactions of them with (un)substituted styrene appeared to be increased from ortho- to para-substitution.
