Two new dibenzotetraaza14]annulenes (DBTAAs) featuring indolenine moieties were synthesised via an acetic acid -catalysed condensation of 1,2-diaminobenzene with two diformyl indolenines in good yields. The structural identity of the compounds was confirmed by NMR ( 1 H, 13 C), FT-IR and elemental a...
