Synthesis of 2,3‐dihydroquinazolin‐4(1H)‐ones in the presence of Fe3O4@nano‐cellulose–OPO3H as a bio‐based magnetic nanocatalyst

In this research, we have used Fe3O4@nano‐cellulose–OPO3H as magnetic bio‐based nanocatalyst for the synthesis of 2,3‐dihydroquinazolin‐4(1H)‐ones via condensation of 2‐aminobenzamide and different aldehydes. The major advantages of the present methodology are good yields, ecofriendly catalyst, and easy workup.
