## Abstract Several pairs of diastereoisomeric open‐chain 1,2:3,4‐diepoxides with different substitution patterns were prepared (see 3–9). As far as possible, crystal structures were determined to corroborate the relative configurations and to give insight into the solid‐state conformations of thes
