Abstract
A gold-catalysed cycloisomerization of 1,5-diynes is described, which offers a selective approach to access 1,3,4-trisubstituted pyrroles. In this reaction, the cationic gold catalyst activates the ynamide moiety, initiating the cycloisomerization to produce the pyrrole core, and H2O acts as an external nucleophile to trap the vinyl cationic species, thus leading to the formation of 1,3,4-trisubstituted pyrroles with high selectivity.

Abstract
Over the last decade, there has been an increasing effort to fight inflammatory conditions establishing new multitarget approaches. Chronic inflammation is implicated in many multifactorial diseases, constituting a great economic burden and a chronic health problem. In an attempt to develop new potent multifunctional anti-inflammatory agents, a cinnamic-pyrrole hybrid (6) was synthesized and screened for its antioxidant and anti-Lipoxygenase potential. The new compound, in comparison with its pyrrole precursor (4), showed improved biological activities. In silico calculations were performed to predict its drug-likeness. The examined derivative is considered orally bioavailable according to Lipinski’s rule of five. Compound 6 could be used as a lead for the synthesis of more effective hybrids.

Abstract
A mechanochemical van Leusen pyrrole synthesis with a base leads to 3,4-disubstitued pyrroles in moderate to excellent yields. The developed protocol is compatible with a range of electron-withdrawing groups and can also be applied to the synthesis of oxazoles. Attempts to mechanochemically convert the resulting pyrroles into porphyrins proved to be difficult.

Abstract
BACKGROUND Due to the presence of both five-membered heterocyclics like pyrrole and thiophene in one molecule considerable attention was made for their enormous pharmacological activities out of which include anti-inflammatory and anti-ulcer activities. OBJECTIVE Chalcones with toluenesulfonylmethyl isocyanide (TosMIC) undergo synthesis to form some new aryl (4-aryl-1H-pyrrol-3-yl) (thiophen-2-yl) methanone derivatives. Molecular docking of synthesized compounds with protein receptors of anti-inflammatory COX-1(3N8Y), COX-2 (1PXX) along with anti-ulcer H+/K+ATPase enzyme (2XZB) followed with drug-likeness, and in silico ADMET properties. MATERIALS AND METHODS The multicomponent reaction was carried out by the intermediate formation of α, β-unsaturated ketone from carbonyl compounds which on sequential addition undergoes [3+2] cycloaddition reaction in same medium affords aryl (4-aryl-1H-pyrrol-3-yl) (thiophen-2-yl) methanone derivatives by addition of TosMIC in basic medium had resulted in series of compounds PY1 to PY12. All the new synthesized compounds were screened for their in-vitro anti-inflammatory activity by bovine serum albumin method followe with COX assay, and in-vivo by using carrageenan-induced rat paw edema method of the selected compounds PY1, PY5 and PY12 which is also screened for anti-ulcer activity by pylorus ligation method, respectively. Molecular docking was performed using autodock tools, drug-likeness by OSIRIS property explorer and admetSAR properties. RESULTS AND DISCUSSION From the synthesized compounds of aryl (4-aryl-1H-pyrrol-3-yl) (thiophen- 2-yl) methanone derivatives PY5 showed decent in-vitro and in-vivo anti-inflammatory along selectivity index of 6.2 for COX-1 with IC50(μM) value of 9.54 over diclofenac with 8.74 and PY1 showed decent in-vivo anti-ulcer activities along with drug-likeness and in silico ADMET predictions revealed that all the synthesized compounds have minimal toxic effects with good absorption as well as solubility characteristics. The selected compounds may serve as potential lead compounds for developing new anti-inflammatory and anti-ulcer drugs. CONCLUSION From the newly synthesized molecules PY5 was found to be effective for anti-inflammatory and PY1 was found to be effective for anti-ulcer activities further derivitization and designed of modification to achieve more compounds with potent anti-inflammatory and anti-ulcer activities.

Abstract
An up-to-date short review of the chalcone methodologies is presented, which is the most
interesting and beneficial for choosing the desired protocol to synthesize suitable derivatives of chalcones.
Chalcones are fluorescent, stable compounds which contribute to the synthesis of various
pharmacologically important heterocyclic structure-based derivatives. Chalcone has displayed a remarkable
curative efficiency to cure several diseases. Several schemes and methodologies have been
reported for employing different catalysts and reagents. The development of improved methodologies
of α, β-unsaturated carbonyl compounds is still on going. In this review, synthetic methodologies
and their recent modification in designing new methods with efficient, economical, eco-friendly
and high yield are discussed.

Abstract
Pyrrole and its polysubstituted derivatives are important five-membered heterocyclic compounds, which exist alone or as a core framework in many pharmaceutical and natural product structures, some of which have good biological activities. The Van Leusen [3+2] cycloaddition reaction based on tosylmethyl isocyanides (TosMICs) and electron-deficient compounds as a substrate, which has been continuously developed due to its advantages such as operationally simple, easily available starting materials, and broadly range of substrates, is one of the most convenient methods to synthetize pyrrole heterocycles. In this review, we discuss the different types of two carbon synthons in the Van Leusen pyrrole reaction and give a summary of the progress of these synthesis methods in the past two decades.
