Abstract

Abstract A study on the acetylation and benzoylation of title compounds by quenching the corresponding 4-carbanions with acyl chlorides or esters is reported. The obtained ketones are formed as minor regioisomeric adducts in the cycloadditions of benzo and mesitonitrile oxide to methyl and phenyl vinyl ketone. The quenching with methyl chloroformate was also examined as a possible convenient route to 4-methoxycarbonyl-3-aryl-4, 5- ...
