WebJan 4, 2024 · As already stated (Chart 8.1), the fused ring compounds may contain two rings (bicyclic compounds) or more than two rings (polycyclic compounds).. 2.1 Fused Ring Compounds Containing Two Rings (Bicyclic Compounds). The smallest fused ring compound containing two rings isbicyclo[1.1.0] butane (Fig. 8.1a). It is a strained … WebTo get the number of fused ring systems, you'd go through the SSSR (smallest set of smallest rings) and see if a ring bond is also a member of another ring. If so, that's a fused ring system. You'd then need to do graph traversal to find all ring bonds in the fused ring system (i.e., in cholesterol there's only one fused ring system).
