A reaction in organic chemistry that creates either furans, pyrroles, or thiophenes from 1, 4-
dicarbonyl compounds is called Paal–Knorr synthesis. It is a synthetically valued process for …

In the current scenario for continuous requirement of better drugs, medicinal chemists must
visage the challenging task of preparing novel patentable compounds, combining high …

2-(Methylthio)-1, 4-diaryl-2-butene-1, 4-dione (3) are prepared from readily available aryl
methyl ketones in the presence of copper (II) oxide, iodine, and dimethyl sulfoxide. The …

Several di-and triarylfuran derivatives were prepared in high yields from but-2-ene-1, 4-
diones/but-2-yne-1, 4-diones using formic acid in the presence of a catalytic amount of …

Several pyrrole derivates with multiple aryl substituents were prepared conveniently in a one
pot-reaction from but-2-ene-1, 4-diones and but-2-yne-1, 4-diones via hydrogenation of the …

A facile approach to 6-aryl/alkyl substituted 6 H-indolo [2, 3-b] quinolines from mono-N-
substituted isoindigo derivatives in the presence of SnCl2· 2H2O in acid media is described …

An efficient and unprecedented strategy for the synthesis of 1, 4-enediones from saturated
ketones has been developed via palladium-catalyzed oxidative dehydrogenation. The …

The first straightforward strategy for the synthesis of 1, 4-dicarbonyl Z-alkenes has been
developed via an electrochemical cross-coupling reaction of sulfoxonium ylides and alkynes …

The Pd0‐catalysed cross‐coupling of intact pyrroles with various reaction partners is
