Pyrrole studies part 41. Reactivity of 3, 4-diformyl-2, 5-dimethylpyrrole with diaminoalkanes. An unusual formation of 2-azafulvenes
(Pergamon, 1989)3,4-Diformyl-2,5-dimethylpyrrole (1) reacts with α,ω-diamino-alkanes, NH2(CH2)nNH2t' to form either the potentially tautomeric 2:2 macrocyclic adduct (7a) ⇌ (8), when n = 2, or the potentially tautomeric 1:1 bicyclic adduct ... -
Pyrrole studies part 47. C NMR Spectroscopic characterisation of the products of the reaction of formylpyrroles with aniline and diaminobenzenes
(2000)Pyrrole-3, 4-dicarboxaldehydes react with aniline to produce" bis-imines" having a 3H-pyrrole structure, 3b. In contrast, pyrrole-2-carboxaldehyde and pyrrole-2, 5-dicarboxaldehydes produce 1H-pyrrolylmethylenimines. ...
