Synthesis of β-nitropyrroles based on nitro compounds (review)

Nitropyrrole natural products: isolation, biosynthesis and total synthesis

“…28 The synthesis of a selection of other unnatural β-nitropyrrole compounds has been reviewed by Sagitullina and coworkers. 29 3. α-Nitropyrrole-containing natural products: heronapyrroles and nitropyrrolins…”

The rearrangement of 3-nitropyridinium salts to 3-nitropyrroles

“…[25][26][27][28][29] The extraordinary biological and synthetic significance of compounds of the pyrrole series is a powerful stimulus to motivation the development of new approaches to the synthesis of these compounds. [30][31][32][33][34] In this paper we present novel results of our investigations of the nitropyridinium salt rearrangement to 2-acyl-4-nitropyrroles.…”
