The measurements point to the presence of traps exponentially dibtributed over a wide energy range. Currents are found to vary with temperature in these samples exhibiting low activation energies. The activation energy decreases from naphthalene&nb

AbstractObjectiveThe aim of this study was to synthesize ten 1,4-dihydropyridine (DHP) derivatives in which substituted cyclohexane rings were fused to the DHP ring and to determine how different ester groups and the benzoyl substituent introduced in 4-phenyl ring affected their calcium channel blocking activity.MethodsA microwave-assisted one-pot method was applied for the synthesis of compound1–5according to a modified Hantzsch reaction. The benzoyl moiety was introduced in the 4-phenyl ring of these dihydropyridines by refluxing with benzoyl chloride in acetone in the presence of anhydrous

Abstract:

Thirty-six new stabilised phosphonium ylides designed to undergo thermal loss of Ph3PO and radical domino cyclisation have been prepared and are generally found to undergo the desired reaction under flash vacuum pyrolysis conditions at 850 °C. A wide range of tetra- and pentacyclic fused-ring heterocycles, many previously unknown, are thus formed in moderate to high yield in a single step. By using suitably substituted starting materials, substituents such as CH3 and Cl can be installed at various positions in the products. The method has also been demonstrated in a combinatorial mode to gene

Abstract:

Synthesis and flash vacuum pyrolysis (FVP) of stabilised phosphorus ylides containing an o-amino functionalised benzene ring has been examined for the first time. Model studies using N-methyl-N-tosyl and N-mesyl-N-methyl ylides showed that the ylides could be prepared, although yields were variable, and had the expected spectroscopic properties. Upon FVP, however, the expected loss of Ph₃PO and the sulfonyl group was accompanied by unexpected transfer of the reactive site from nitrogen to carbon giving 3- substituted quinolines rather than the expected indole products.

Abstract:

Heterocyclic compounds are essential in the metabolism of all living cells, and most nitrogen-containing fused heterocyclic compounds with five-membered rings are biologically active. Nitrogen and sulphur-containing heteroaromatic compounds, such as imidazothiazoles and their derivatives, are acknowledged for their biological activity and substantial contributions to medicinal chemistry. Imidazothiazoles are defined by their fused bicyclic structure, merging an imidazole ring (a five-membered ring with two non-adjacent nitrogen atoms) with a thiazole ring (a five-membered ring containing both

Five-membered heteroaromatic ring fused pyridine derivatives are of increasing interest in drug design and medicinal chemistry. The structural similarity of many drugs (especially antiviral and anticancer ones) with DNA bases such as adenine and guanine is a key factor to explain their effectiveness. Apart from these, it is also found in the structures of substances with antituberculosis, antibacterial, antifungal, anti-inflammatory, and antimalarial activities. Another advantage of this group of compounds is their positive contribution to solubility, polarity, lipophilicity, and hydrogen bond
