Romero-Reyes, Moises A.,Zaragoza-Galicia, Ivann,Olivo, Horacio F.,Romero-Ortega, Moises
, p. 9515 - 9519 (2016/10/14)
A simple and easy reduction of trichloroacetyl compounds following the modification of Appel's reaction protocol, using triphenylphosphine and methanol, afforded the corresponding dichloroacetyl compounds, with the exception of trichloroacetylmorpholine,
Solvent free synthesis of 2-acylpyrroles and its derivatives catalysed by reuseable zinc oxide

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.
Enantioselective synthesis of heteroaromatic epoxyketones under phase-transfer catalysis using D-glucose- and D-mannose-based crown ethers

Heteroaromatic epoxyketones have been synthesized in an asymmetric Darzens condensation of 2-chloroacetylfuran or 2- and 3-chloroacetylthiophene with aromatic aldehydes and in the enantioselective epoxidation of α,β-enones with an N-methylpyrrole unit, in
Spectroscopic and theoretical studies on some new pyrrol-2-yl-chloromethyl ketones
Dubis, Alina T.,Domagala, Malgorzata,Grabowski, Slawomir J.
experimental part, p. 556 - 566 (2010/06/13)
A novel series of pyrrole-2-yl chloromethyl ketones were synthesized and studied by FT-IR, 1H, 13C NMR spectroscopy and DFT calculations at the B3LYP/6-311++G(d,p) level of approximation. Two stable conformations were detected in solution: s-cis and s-trans forms where the C=O group is located on the same side or the opposite side of N-H group, respectively. The conformational stability of these molecules is governed mainly by intermolecular hydrogen bonding interactions. The strength of hydrogen bonds was evaluated on the basis of 1H chemical shift and infrared red shift ΔνN-H of the stretching vibration of N-H proton donating bonds. The quantum theory of 'atoms in molecules' as well as the natural bond orbital method were applied to characterize hydrogen bonding interactions.

Selective α-Chlorination of Acetylpyrroles
Croce, Piero Dalla,Ferraccioli, Rafaella,Ritieni, Alberto
, p. 212 - 213 (2007/10/02)
Reaction of acetylpyrroles with benzyltrimethylammonium dichloroiodate in tetrahydrofuran solution leads to the corresponding α-chloro derivatives with high selectivity and good yields.
Direct Vilsmeier-Haack Chloroacetylation of Pyrroles
Croce, Piero Dalla,Rosa, Concetta La,Ritieni, Alberto
, p. 783 - 784 (2007/10/02)
Reaction of pyrroles with N,N-dimethyl-2-chloroacetamide in the presence of phosphorus oxychloride leads to a mixture of 2- and 3-chloroacetylpyrroles, which can be separated by chromatography.
