{ALF} Reactive dienophile. For a review of its Diels-Alder reactions, see: Org. React., 4, 1 (1948). For examples, see: Org. Synth. Coll., 3, 807 (1955); 4, 890 (1963). For reaction with Danishefsky's diene (1-Methoxy-3-trimethylsiloxy-1,3-butadiene, L14672), see: Org. Synth. Coll., 7, 312 (1990).

{ALF} For use in combination with Urea hydrogen peroxide adduct, L13940, to generate peroxymaleic acid in epoxidation and Baeyer-Villiger reactions, see: Heterocycles, 36, 1075 (1993). Peroxymaleic acid can also be generated in situ from maleic anhydride and 30% H2O2 in NMP, and has been found to be a very effective oxidant for conversion of sulfides to sulfoxides. For a study of stoichiometric and catalytic oxidations with this system, see: J. Org. Chem., 61, 5693 (1996).
