Explore: Cyclisation

A cyclic compound (or ring compound) is a term for a compound in the field of chemistry in which one or more series of atoms in the compound is connected

empirical evidence and numerous "exceptions" are known. Examples include: cyclisations of cations reactions involving third-row atoms, such as sulfur Transition

Monosaccharides (from Greek monos: single, sacchar: sugar), also called simple sugars, are the simplest forms of sugar and the most basic units (monomers)

is then formed in a second step by reductive cyclisation. In the above scheme, the reductive cyclisation is affected by Raney nickel and hydrazine. Palladium-on-carbon

The Nazarov cyclization reaction (often referred to as simply the Nazarov cyclization) is a chemical reaction used in organic chemistry for the synthesis

elongase inhibition, and inhibition of geranylgeranyl pyrophosphate (GGPP) cyclisation enzymes, part of the gibberellin pathway. It is marketed under the trade

The Borsche–Drechsel cyclization is a chemical reaction used to synthesize tetrahydrocarbazoles by the acid-catalyzed cyclization of cyclohexanone arylhydrazones

Radical cyclization reactions are organic chemical transformations that yield cyclic products through radical intermediates. They usually proceed in three

has high atom economy. Many variations have been developed, including cyclisation of mixtures of alkynes and alkenes as well as alkynes and nitriles. Trimerisation

of dilution, acyloin condensation of a diester favours intramolecular cyclisation (for all but the smallest rings) over intermolecular polymerisation.
