Heterocyclic Esters of 1,1'-Ferrocenedicarboxylic Acid

Аннотация

Acylation of hydroxyl-containing heterocyclic compounds with 1,1'-ferrocenedicarbonyl chloride afforded diheteryl-1,1'-ferrocenedicarboxylates. Bisaldehyde-containing diesters were obtained by acylation of hydroxybenzaldehydes. The condensation of the latter with 2-naphthylamine or 4-phenylazoaniline resulted in the formation of the corresponding azomethines. The reduction of bisaldehyde-containing diesters furnished ferrocene-containing diols. Ferrocene tetrahydrobenzo[a]acridine-11-(7H)-one derivatives were synthesized as a result of the three-component cascade heterocyclization of ferrocene bisaldehyde-containing diesters with 2-naphthylamine and dimedone.
