Convenient decagram scale preparation of ethyl 3,4-diethylpyrrole-2-carboxylate, a versatile precursor for pyrrole-based macrocycles and chromophores
Herein, we describe a detailed preparation of the versatile pyrrole building block 3,4-diethylpyrrole-2-carboxylate (1), a key structural feature in various porphyrins, porphyrinoids, and other chromophores. 1 was prepared via a one-pot DBU catalyzed Henry reaction and acid catalyzed acetylation fol...
