The low-temperature Grignardreaction of mixed carboxylic anhydrides derived from acid chlorides and o-anisic acid to the general synthesis of keto esters is demonstrated for compounds 1–6, although, some limitations on substrate and Grignardreagent species are also encountered; attempts in the oxa series 2 are unsuccessful, and reaction with ω-phenylpropyl Grignard species for 1 and 4 shows a drastic
