Kòm gwosè a gwosè ogmante, varyete nan konpoze yo ki ka jwenn nan varye kote a, di ki kalite, ak kantite heteroatoms ogmante enormously. Sepandan, chimi de heterocycles ak zanno 7-générales ou plis ki pi piti devlope pase sa de 6 Et 5-génération konpoze heterocyclic bag.

As the ring size increases, the variety of the compounds that may be obtained by varying the location, type, and the number of heteroatoms increases enormously. However, the chemistry of heterocycles with 7-membered rings or more is less developed than that of 6 and 5-membered ring heterocyclic compounds.
