1,2,3-Triazolyl-tetrahydropyrimidine Conjugates as Potential Sterol Carrier Protein-2 Inhibitors: Larvicidal Activity against the Malaria Vector Anopheles arabiensis and In Silico Molecular Docking Study

Molecules, 2022
Alteration of insect growth regulators by the action of inhibitors is becoming an attractive strategy to combat disease-transmitting insects. In the present study, we investigated the larvicidal effect of 1,2,3-triazolyl-pyrimidinone derivatives against ...

Photochemical Transformations of Tetrazole Derivatives: Applications in Organic Synthesis [PDF]

, 2010
Tetrazoles remain a challenge to photochemists. Photolysis leads to cleavage of the tetrazolyl ring, may involve various photodegradation pathways and may produce a diversity of photoproducts, depending on the structure and conformational flexibility of

Syntheses and Studies of Metaphase-Arresting Pyrimidinones. [PDF]

Acta Chemica Scandinavica, 1991
Methods are described for the syntheses of chloromethyl hydroxyalkylphenyl and benzyl ethers, and for the synthesis of bromomethyl phenyl ketone analogs. The hydroxy groups were protected as acetates. The halogenomethyl derivatives have been used for N-alkylation of 5-chloro-2(1H)-pyrimidinone.
