[ 1 ] - An Efficient Synthesis of 4H-chromene Derivatives by a One-pot, Three-component Reaction
A facile and efficient one-pot, multicomponent synthesis of 4H-chromenes is reported, through the reaction of arylglyoxalmonohydrates with 1,3-diketones and malononitrile in eTEMPthanol in the presence of L-proline as a catalyst.
[ 2 ] - Synthesis of a New Series of 4H-benzo[h]chromenes by a Multicomponent Reaction under Solvent-Free Microwave Conditions
Multicomponent condensation of 1-naphthol, malononitrile, and arylglyoxals in the presence of Mg-Al hydrotalcite under solvent-free MicroWave (MW) conditions gave a new series of 2-amino-4-aroyl-4H-benzo[h]chromene-3-carbonitriles in high yields (70-89%). The structure of all products was elucidated by their...
