The Mannich condensation of amino acids with 3-phenoxychromones and polyhydroxy-α-phenoxyacetophenones has given a series of 8-carboxyalkylaminomethylchromones and 3-carboxymethylaminomethyl-2,4-dihydroxy-α-phenoxyacetophenones. Some features of the course of the Mannichreaction as a function of the structures of the chromones and acetophenones have been studied.

e (IIa-o), containing both electron-donor and electron-acceptor substituents in the phenoxyl part of the molecule. These compounds were obtained by the action of phosphorus chloride on the complex of the compound (Ia-o) with boron trifluoride etherate in dimethylformamide. The acylation of the compound (II) with acetic anhydride in the presence of pyridine gave the corresponding acetates (IIl).
