The stereodifferentiating potential of arabinosyl aldimines was utilized in stereoselective syntheses of 2-substituted dehydropiperidinones and their further transformation to 2,6-cis-substituted piperidinones. The absolute configuration was proven by X-ray analysis and by the synthesis of the enantiomerically pure alkaloid (+)-dihydropinidine. The presented method offers the possibility to synthesize
阿拉伯糖醛亚胺的立体分化潜力可用于立体选择性合成 2-取代脱氢哌啶酮及其向 2,6-顺式取代哌啶酮的进一步转化。通过 X 射线分析和对映体纯生物碱 (+)-二氢吡啶的合成证明了绝对构型。所提出的方法提供了合成哌啶衍生物对映异构体的可能性,这些衍生物是通过应用相应的半乳糖胺辅助剂获得的。
