Abstract
In the present study, we have introduced an efficient solvent-free protocol for the synthesis
of glycosyl annulated phosphorylated/thiophosphorylated 1,2,3-triazole derivatives using
reusable CuFe2O4 magnetic nanoparticles as a heterogeneous catalyst with the protocols of popular
click chemistry approach. Quantum chemical calculations of all the reactants and products
have been calculated using density functional theory with Spartan-18 software. In addition, the
molecular docking studies of all the glycosyl annulated phosphorylated/thiophosphorylated 1,2,3-
triazole derivatives have been studied as effective fungicides against CaCYP51 (PDB ID 5EQB),
protein of P. infestans effector target site (PDB ID: 2NAR), and SsCYP51(PDB code: 6CR2) using
Autodock Vina and Discovery Studio software. Among the three different proteins, the binding
energies of the compounds (5a-d) with CaCYP51 (PDB ID 5EQB) have shown better results
in the range of 7.0 to 7.4 kcal/mol. Hence, these compounds may be used as strong fungicides for
the inhibition of CaCYP51 (PDB ID 5EQB). In conclusion, the synthesized compounds may be
better useful in agrochemical applications as vital fungicides.
