Abstract: N-Phenyl- and N-(3,5-dichlorophenyl)maleimide react smoothly with furan to give endo and exo adducts depending on the reaction temperature. Semiempirical quantum-mechanical methods AM1 were used to rationalize this formation of adducts. The reduction of exo Diels-Alder adducts with sodium borohydride proceeds stereoselectively to yield the exo or endo hydroxylactams depending on the reaction temperature. 1,5-Dipolar cycloaddition of arylnitrile oxides to exo Diels-Alder adducts led exclusively to exo-exo cycloadducts.
