To find out whether the 1,4‐addition to 1,2:3,4‐diepoxides, which so far has been observed only once, is of a more general character, we investigated the reaction of a variety of O‐, C‐, N‐, and S‐nucleophiles with the model compound 1,2:3,4‐diepoxy‐2,3‐dimethylbutane (Scheme 4). In several cases, 1,4‐addition products could, indeed, be observed besides the expected 1,2‐adducts (Table).
