Naming bicyclic systems
WitrynaA general approach to the synthesis of (6:5:6) fused heterocyclic ring systems involves intramolecular cyclization of two substituents attached to a five-membered ring of the fused (6:5) system. A typical example is cyclization of 211 to generate an imine 212, which undergoes hydrolysis to the tricyclic lactone 213 ( Scheme 8) <1998CPB1632>. WitrynaBicyclic Ring Systems There are three ways to join two rings. If two rings share two or more atoms, then the structure is called a bicyclic compound. If the two rings share a single atom, then the structure is called a spirocyclic compound. Examples of each way to join rings is shown below. Bicyclic Compounds

Witryna24 wrz 2024 · Polycyclic Compounds Hydrocarbons having more than one ring are common, and are referred to as bicyclic (two rings), tricyclic (three rings) and in general, polycyclic compounds. The molecular formulas of such compounds have H/C ratios that decrease with the number of rings. Bicyclic molecules are described by IUPAC nomenclature. The root of the compound name depends on the total number of atoms in all rings together, possibly followed by a suffix denoting the functional group with the highest priority. Numbering of the carbon chain always begins at one bridgehead atom (where the rings meet) and follows the carbon chain along the longest path, to the next bridgehead atom. Then numbering is continued along the second longest path and so …
