Scope and limitations in the diastereoselective preparation of 2,6-cis or 2,6-trans disubstituted piperidines are described, through intramolecular reaction of chiral β′-carbamate-α,β-unsaturated ketone. This methodology has been applied to the total synthesis of a few well chosen examples, such as (−)-solenopsine A and alkaloid (+)-241D.
通过手性β'-氨基甲酸酯-α,β-不饱和酮的分子内反应,描述了2,6-顺式或2,6-反式二取代的哌啶的非对映选择性制备的范围和局限性。该方法已应用于一些很好选择的例子的全合成,例如(-)-比尔诺西汀A和生物碱(+)-241D。
