Naming Bicyclic Compounds - Organic Chemistry …

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 … WebThe present disclosure is directed to modulators of SOS1 and their use in the treatment of disease.
