Among some 2-substituted 4H-1,3,2-benzodioxaphosphorin 2-sulfides, the 2-OMe derivative has the sulfur atom mainly in the quasiequatorial position. On the other hand, the conformation in which the sulfur is quasiaxial is favored in the 2-NHMe and 2-Et derivatives. We have done ab initio molecular or

## 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
