Green synthesis of pyrano [3,2-b]pyran derivatives using nano Si–Mg–fluorapatite catalyst and the evaluation of their antibacterial and antioxidant properties
In this study, we synthesize 2-amino-4-alkyl/aryl-6-(hydroxymethyl)-8-oxopyrano[3,2-b] pyran-3-carbonitriles derivatives using a multicomponent reaction featuring aromatic or aliphatic aldehydes, kojic acid, and malononitrile catalyzed by nano fluoroapati
