Allenes are the simplest class of cumulenes, with two contiguous C C bonds, and show
unique physical and chemical properties. These features make allenes particularly attractive …

Chemistry is the science of bond making and bond breaking. A thorough knowledge of these
processes in the course of the chemical reaction lies at the heart of any reaction mechanism …

Cycloaddition reactions belong to one of the most well-investigated and widely used
reactions in synthetic organic chemistry for the construction of (hetero) cyclic compounds in …

Heterocyclic chemistry constitutes an essential branch of organic chemistry and
heterocycles are widely known to display an array of biological properties. Pyrazoles …

1-Azadienes are versatile building blocks for the efficient construction of various N-

Thermal reactions proceed optimally when they are rapidly heated to the highest tolerable
temperature, held there for the shortest possible time and then quenched. This is explained …

The three-component sequential reaction of α, β-unsaturated aldehydes, amines, and
enaminones proceeded smoothly to give 1, 3, 4-trisubstituted 1, 4-dihydropyridines in …

The preparation and application of dihydropyridines continue to attract considerable interest
in organic synthesis and medicinal chemistry. The biological activities and synthetic utility of …

The solvent-free preparation of unsymmetrical N-aryl-5, 6-unsubstituted-1, 4-
dihydropyridines (DHPs) by ball-milling was investigated. Three different mechanochemical …
