A mild, novel, and efficient silyl-promoted conversion of cyclic anhydride to diesters and amide esters. The reaction follows a two-step process, ring opening of anhydride by amine or alcohol following esterification. The reaction was carried out in the presence and absence of base. The method has broad substrate scope and is applicable for the synthesis of commercial plasticizers.
