Unequivocal synthetic routes towards 5- and 6-acyl-2(3H)-benzoxazolones are described. Comparison of the physicochemical properties of the compounds obtained by direct acylation under various Friedel-Crafts reaction conditions always leads to the conclusion that 6-acyl derivatives are the only isolated products. This observation contradicts previously published results.
