General description

2-Ethylpyrrole is a monosubstituted alkyl pyrrole. Stochastic, Rothemund-type condensation of pyrrole, 2-ethylpyrrole and arylaldehyde yields 3-ethyl-substituted inverted porphyrin, which readily converts to 3-(1′-hydroxyethyl)- and 3-acetyl-inverted porphyrins. 2-Ethylpyrrole is a conjugated five-membered heterocyclic flavor compound and its photooxidation reactivity was investigated.

Application

2-Ethylpyrrole may be used in the preparation of 1-(3-methoxyphenyl)-2-ethylpyrrole.

This paper details the copper-catalyzed N-arylation of pi-excessive nitrogen heterocycles. The coupling of either aryl iodides or aryl bromides with common nitrogen heterocycles (pyrroles, pyrazoles, indazoles, imidazoles, and triazoles) was successfully performed in good yield with catalysts derived from diamine
