Synthesis of Iodo-Flavanones and ChromanonesAuthor(s): A. S. Dighade and S. R. Dighade
The mixture of 1-(2-hydroxy-3-iodo-5-methyl phenyl)-3-phenyl-1, 3-propanedione and six different aromatic aldehydes were refluxed in ethanol containing few drops of piperidine for 30 min. Thus synthesized flavanone IIa-IIf. The synthesized compounds were characterized by I.R. and N.M.R. spectral analysis.
