cyclises to lactone 9. Aniline inserts preferentially and exclusively over phenol in a competition reaction with 7 to afford an anilinophosphonoacetate 11. Phenol insertion products 5 are shown to be versatile intermediates in a novel preparation of 2-aryloxy-3-phenylpropenoates 12 by Wadsworth-Emmons reaction with benzaldehydes. Dissolving magnesium metal reduction provides a mild method for the conversion
