A highly efficient procedure for preparing 2-acylpyrroles and its derivatives is described. The products were obtained through regioselective Friedel-Crafts reactions of pyrroles and its derivatives with alkyl or aryl acid chlorides catalysed by zinc oxide under solvent-free conditions. This method has the advantages of green chemistry, operational simplicity, solvent-free conditions, and recoverable catalyst.

experimental part, p. 2039 - 2043 (2010/06/14)
We herein report a novel one-pot reaction for benzoylation of pyrrole. The key step in the reaction is generation of di(1H-pyrrol-1-yl)zirconium(IV) chloride complex which reacts with benzaldehydes and methyl benzoates to give 2-benzoylpyrroles as the major product.
Infrared and Nuclear Magnetic Resonance Properties of Benzoyl Derivatives of Five-membered Monoheterocycles and Determination of Aromaticity Indices
Jeon, Kyu Ok,Jun, Jung Ho,Yu, Ji Sook,Lee, Chang Kiu
, p. 763 - 771 (2007/10/03)
Benzophenones, 2-benzoylthiophenes, 2-benzoylpyrroles, and 2-benzoylfurans, which have substituents at m- and p-positions of the benzoyl ring were prepared and their ir and nmr spectra were obtained in 0.1 M chloroform-d solution. The chemical shift values of each series were plotted against the Hammett substituent parameters to give good correlation, with the exception of the ortho-Hs and -Cs. The slopes as well as the differences in chemical shift gave sets of meaningful values for the indices of aromaticy.

2-Aroyl-4-(ω-aminoacyl)- (4) and 4-aroyl-2-(ω-aminoacyl)pyrroles (9) represent a new, structurally novel class of anticonvulsant agents. Compounds of type 4 were prepared by Friedel-Crafts acylation of a 2-aroylpyrrole with an ω-chloroacyl chloride followed by displacement of the chloro group by a primary or secondary amine. Compounds of type 9 were prepared by Friedel- Crafts aroylation of a 2-(ω-chloroacyl)pyrrole followed by displacement by an amine. These compounds were active in the mouse and rat maximal electroshock tests but not in the mouse metrazole test. The lead compound, RWJ-37868, 2-(4-chlorobenzoyl)-4-(1-piperidinyl-acetyl)-1,3,5- trimethylpyrrole (4d), showed potency and therapeutic index comparable to those of phenytoin and carbamazepine and greater than those of sodium valproate. This compound blocked bicuculline induced seizures, did not elevate seizure threshold following iv infusion of metrazole, and blocked influx of Ca2+ ions into cerebellar granule cells induced by K+ or veratridine.
