Heterocyclic Chemistry Nomenclature Quiz

Heterocyclic Nomenclature

• Heterocyclic compounds are named using the systematic IUPAC nomenclature.

• Monocyclic fused and bridged heterocycles are named using substitutive and/or additive nomenclature.

• Aromatic heterocycles conform to general aromatic rules.

Aromatic Heterocycles

• Aromatic heterocycles exhibit typical aromatic behaviour with respect to structure, reactivity, and spectroscopic properties.

• Classification, spectroscopic properties (e.g., NMR, UV-Vis), aromatic criteria (e.g., resonance energy, delocalisation energy, magnetic susceptibility).

• Reactivity and tautomerism in aromatic heterocycles.

Non-Aromatic Heterocycles

• Small ring heterocycles exhibit strain-induced properties from bond angles and torsional strain.

• Ring inversions and pyramidal inversions are relevant in small ring heterocycles.

Medium-Sized Heterocycles

• Synthesis and reactions of three- and four-membered heterocycles (e.g., aziridines, oxiranes, thiiranes, etc.).

• Synthesis and reactions of benzo-fused five-membered heterocycles (e.g., benzopyrroles, benzofurans, benzothiophenes) including medicinal applications.

Mesoionic Heterocycles

• Classification and properties of mesoionic heterocycles (e.g., types A and B).

Six-Membered Heterocycles with a Heteroatom

• Synthesis and reactions of pyridinium salts, pyrones, quinolinium salts, benzo-fused heterocycles (e.g., coumarins, chromones).

Heterocycles with Multiple Heteroatoms

• Synthesis and reactions of larger (seven or more membered) heterocyclic systems with two or more heteroatoms (e.g., diazines, triazines, tetraazines, thiazines).

• Synthesis and reactions of larger heterocyclic compounds (e.g. azepinens, oxepins, thiepins, diazepines, thiazepines, azocines, diazocines, dioxocines, dithiocines).

Heterocycles Containing Arsenic, Antimony, and Boron

• Introduction, nomenclature, synthesis, and properties of heterocycles containing arsenic, antimony, and boron.
