چکیده
|
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 ft-ir, 1h-nmr, 13c-nmr spectral data and microanalysis
