n→π* Interactions that elicit carbonyl group pyramidalization in five pairs of diastereoisomers (1–5). Structures show non-hydrogen atoms as determined by X-ray crystallography. For computational analyses of n→π* interactions in crystalline 1–5, see Figure S7 and Table S37 in the Supporting Information.
