An Environmental Friendly Approach for the Synthesis of Spiro[indoline-3′,2-quinazoline]2′,4(3<i>H</i>)-dione Using 1-Methylimidazolium Hydrogen Sulfate, as Reusable Catalyst
A facile and environmentally benign procedure for the synthesis of 3‐aryl‐1H‐spiro[indoline‐3′,2‐quin‐azoline]2′,4(3H)‐dione from isatoicanhydride, aromatic amines and isatin derivatives in Brønsted acidic ionic liquid, 1‐methylimidazolium hydrogen sulfate, was reported. The ability to reuse the ionic liquid, the high yield, short reaction time and ease of purification are the important features of

Two series of spiro-oxindole dihydroquinazolinone derivatives have been designed and synthesized using a catalytic amount of nano cerium oxide with excellent product yields by a convenient one-pot process. The synthesized compounds were evaluated for their in vitro antibacterial activity, and compounds 1i-1p showed considerable antibacterial activities to Escherichia coli. Molecular docking of E. coli Biotin Carboxylase (EcBC) enzyme was also performed in order to predict the interactions of the synthesized compounds. (C) 2016 Published by Elsevier Ltd.
