Abstract

The procedure utilizes magnesium chelates as depicted in Scheme I. Treatment of the starting materials A'with magnesium ethoxide yielded the magnesium chelates B, which were isolated as solid materials after evaporation of the solvent. The chelates were then suspended in benzene and reacted with the acid chlorides. Although intermediates B possess three nucleophilic sites, it is to be expected that the coordination of the two ...
