2-Hydroxy-2-methyl-2H-1-benzopyran-3-carboxamide Derivatives produced by Knoevenagel Condensation†

Abstract

The reaction of 2-hydroxybenzaldehydes with 3-oxobutanamide affords 2,4-dihydroxy-2-methyl-2H-3,4-dihydro-1-benzopyran-3-car boxamides and 2-hydroxy-2-methyl-2H-1-benzopyran-3-carboxamides, depending on the particular aldehyde and the experimental conditions used.
