2-dehydropiperidines with the "ate" complex of DIBAL-H and n-BuLi affords functionalized trans-2,6-disubstituted piperidines. This methodology was employed in the asymmetric synthesis of the quinolizidine alkaloid (-)-lasubine I.
[反应:见正文]用DIBAL-H和n-BuLi的“ ate”复合物对1,2-脱氢哌啶进行羟基定向还原,得到官能化的反式2,6-二取代哌啶。该方法用于喹唑烷生物碱(-)-lasubine I的不对称合成中。
