説明
Abstract When 1-bromo-4-acyloxybutanes having electron-withdrawing groups at 1-position, which were obtained by Cu(I)-catalyzed photochemical addition of 1-bromo-2-acyloxyethanes to electron-deficient olefins, were subjected to treatment with potassium t-butoxide, 2,7-dioxabicyclo[4.1.0] heptanes were obtained.
