  methodology offers a mild approach to obtain a library of 2-amino-4H-pyrans with good yields and favorable function group tolerance. Moreover, molecular docking experiments have been carried out to investigate the possible mechanism of this enzyme-initiated one-pot reaction. In addition, eight compounds in the library have been chosen in order to evaluate the in vitro antitumor activities against three

  Diethylene glycol-bis(3-methylimidazolium) dihydroxide [DiEG(mim)(2)[OH](2) was prepared by the reaction between sodium hydroxide and diethylene glycol-bis(3-methylimidazolium) dibromide in aqueous ethanol at room temperature. This solid, quaternized ionic liquid was employed as a recyclable catalyst for the synthesis of 4H-pyrane derivatives in high yields from the three-component condensation reaction of malononitrile, aromatic aldehydes, and 1,3-dicarbonyls in water at room temperature. In addition, spiropyrane derivatives were synthesized from the reaction of isatin, malononitrile, and 1,3-dicarbonyls in water at reflux. The dicationic ionic liquid showed the same efficiency when used in consecutive reactions. (C) 2015 Elsevier Ltd. All rights reserved.
