On the first one-pot general synthesis of novel 3-benzal-2,3-dihydro-4H-benzopyran-4-ones

The base-catalysed condensation reaction between 2-hydroxyacetophenone and aryl aldehyde gives the corresponding chalcone and flavanone as the products and not 3-arylideneflavanone, as claimed by Chawla and Sharma . 3-Benzylidenflavanones (flavindogenides) are obtainable by acid-catalysed condensation between a flavanone and an aryl aldehyde.
