Pyrazolidine is a saturated organic heteromonocyclic parent. Pyrazolidines are important synthetic intermediates in organic synthesis. Pyrazolidine compounds are valuable heterocyclic compounds due to their powerful biological properties.
Pyrazoles are organic compounds of the general formula C3H3N2H. It is a five-membered heterocycle consisting of three carbon atoms and two adjacent nitrogen atoms. As an H-bond-donating heterocycle, pyrazole has been used as a more lipophilic and metabolically more stable bioisomer of phenol. Pyrazoles have attracted more and more attention due to their broad spectrum of action and strong efficacy.
