Abstract
A high-yielding, efficient, one-pot, three-components (-dicarbonyls – activated cyanomethylenes – aldehydes) synthesis of functionalized 2-amino-4H-pyrans mediated by -Zr(KPO4)2 is reported. The protocol showcases an excellent versatility since it is applicable to aromatic, aliphatic and ,-unsaturated aldehydes under solvent free conditionsFile in questo prodotto:
