The two enantiomeric 2a-methyl-adamantan-4-one have been synthesized by different methods. The contributions to the Cotton effect of an axial Me group in β-position of a cyclohexanone is practically zero, though a pronounced fine structure is found in unpolar solvents.
两种对映体2一甲基-
金刚烷-4-酮已经通过不同的方法合成。尽管在非极性溶剂中发现了明显的精细结构,但在
环己酮的β位置对轴向Me基的Cotton效应的贡献实际上为零。
