Pyrrole chemistry. XXVIII. Substitution reactions of 1-(phenylsulfonyl)pyrrole and some derivatives
Hugh J. Anderson,Charles E. Loader,Ru Xun Xu,Nghia Lê,Niall J. Gogan,Robert McDonald,Louise G. Edwards +6 more
TL;DR: The preparative value of the 1-(phenylsulfonyl) N-blocking and directing group for the synthesis of 3-acylpyrroles has been further evaluated in this article.

The Synthesis of 3-Substituted Pyrroles from Pyrrole
TL;DR: In this article, the reaction d'electrophiles avec le pyrrole se fait preferentiellement in position 1 ou 2; pour obtenir des derives substitues en 3, on protege d'abord la position 1 or 2 par des substituants orientant la reaction en position 3 ou on utilise en position 2 des substitutes permettant un rearrangement conduisant aux pyrroles substituees en 3.

Pyrrole chemistry XXV: A simplified synthesis of some 3-substituted pyrroles
TL;DR: In this paper, a new synthesis of 3-aroyl, 3-acetyl, and 3-nitro-pyrroles from pyrrole utilizing the 1-benzenesulfonyl group as a blocking group was reported.

Pyrrole chemistry. XXIII. The cyanation of substituted pyrroles with chlorosulfonyl isocyanate (CSI). New syntheses of pyrrole-3-carbonitriles
TL;DR: Chlorosulfonyl isocyanate (CSI) reacts not only with pyrrole itself but also with other pyrroles having electron-withdrawing groups in the 2-position as discussed by the authors.

Pyrrole chemistry. XXI. Synthetic approaches to cyanopyrroles
TL;DR: The Vilsmeier-Haack reaction with pyrrole and 1-methylpyrrole has been modified to provide a direct synthesis of the corresponding 2-nitriles as mentioned in this paper.
