  An Efficient Oxidative Difunctionalisation of 2-Amino-2H-chromene and Antimicrobial Activity of the Synthesized Tetrahydrochromene Derivatives

  摘要：

  A novel series of 3-amino-2,2-dialcoxy-7,7-dimethyl-5-oxo-4-phenyl-3,4,5,6,7,8-hexahydro-2H-chromene-3-carbonitriles are synthesized by oxidative difunctionalization (geminal dialkoxylation and migration of the amino group) of 2-amino-4-aryl-7,7-dimethyyl-5-oxo-5,6,7,8-tetrahydro-4H-chromene-3-carbonitriles in the presence of iodobenzenediacetate in water medium with excellent yields. All the newly synthesized compounds are characterized by IR, H-1 and C-13 NMR and Mass spectral data. The representative synthesized analogues are screened in vitro for antibacterial and antifungal activity using Gentamycin sulphate and Nystatin as standard drugs.
