trans-2-(N-benzyl)amino-1-cyclohexanol by hydrogenation and subsequent derivatization give access to a broad variety of diversely substituted derivatives. Furthermore, the corresponding cis isomers are readilyavailable. Applications of these optically active aminocyclohexanols in catalyzed asymmetric phenyl transfer reactions to benzaldehydes and transfer hydrogenations of aryl ketones lead to products with

dicobalt octacarbonyl under CO pressure. The active catalyst, cobalttetracarbonyl anion, induces nucleophilic ring opening of the heterocycle, resulting in inversion of configuration. The regio- and stereospecificity of this reaction resulted in the synthesis of the first highly strained trans-7-azabicyclo[4-2-0]octan-8-one derivatives.
β-内酰胺是通过在 CO 压力下由八羰基二钴催化的氮丙啶羰基化扩环合成的。活性催化剂四羰基钴阴离子诱导杂环亲核开环,导致构型反转。该反应的区域和立体特异性导致第一个高度紧张的 trans-7-azabicyclo[4-2-0]octan-8-one 衍生物的合成。
