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.

Tetrahydrothiophene is a sulfur-containing saturated heterocyclic compound obtained by catalytic hydrogenation of thiophene. After thiophene is reduced to tetrahydrothiophene, it no longer has a conjugated system and aromaticity. Therefore, tetrahydrothiophene shows the properties of general thioethers. Easily oxidized to sulfoxides and sulfones. Tetrahydrothiophene can be used as a raw material for the production of pharmaceuticals, pesticides and photochemicals.
Boronic acids and boronate esters are commonly used reagents in Suzuki–Miyaura coupling chemistry. Organoboron derivatives are common reagents for C–C bond formation, either through classical palladium-mediated transformations or through other newer coupling methods. Boronic esters and acids are potential intermediates in the manufacture of many active pharmaceutical ingredients (API).
