Bicyclo[3•2•2]nonan-6,8-dione has been synthesized as an example of a molecule in which the cyclohexane-1,4-dione ring is constrained to non-chair forms. The synthesis includes the double decarboxylation of the corresponding bridgehead diacid. This reaction is consistent with a new formulation of Bredt's Rule. Conformational studies suggest that the title compound exists in solution as an equilibrium
Bicyclo[3•2•2]nonan-6,8-dione 作为分子的一个例子已经合成,其中环己烷-1,4-dione 环被限制为非椅子形式。该合成包括相应桥头二酸的双脱羧。这种反应与 Bredt 规则的新表述是一致的。构象研究表明标题化合物以两种扭曲形式的平衡混合物存在于溶液中。
