A combination of X-ray crystallographic, 1H, 13C NMR and IR spectroscopic, and computer-modelling techniques have been used to explore both configurational and conformational aspects of the structures of a series of substituted 2-amino-3-(2-hydroxybe

The dimethylamine-mediated ring-opening of a series of N,N-dimethyl-4-oxo-4H-chromene-2-carboxamides to the corresponding (E)-2-(N,N-dimethylamino)-3-(2-hydroxybenzoyl)acrylamides has been monitored by UV spectroscopy, and a mechanistic sequence whic

Chromone-2-carboxylic acids are efficiently transformed into the N, N-dimethylcarboxamides, without concomitant formation of unwanted products, by reacting the corresponding acid chlorides with dimethylammonium chloride in pyridine.

Temperature dependent splitting of N-alkyl 1H and 13C NMR signals in a series of 4-oxo-4H-chromene-2-carboxamides has been analysed in terms of rotation of the amide group. Rotational barriers have been calculated from dynamic 1H NMR data and the con
