The synthesis and CD of various optically active β-substituted adamantanones and adamantanediones are described. All “equatorial” substituents obey the octant rule for ketones, whereas the “axial” ones (with the exception of OH) show antioctant behaviour. The “axial” methoxy adamantanone (8) gives pronounced fine structure in unpolar solvents, the sign of its CD depends on the solvent used. The vicinal

金刚烷酮(8)在非极性溶剂中具有明显的精细结构,其CD的符号取决于所用的溶剂。这些1,5-二酮的毒害作用是相当大的。N原子上的正电荷会产生抗
