The synthesis of enantiopure cis- and trans-2,3-disubstituted piperidines 4 is described. The key step of the synthesis involves the stereoselective reduction of chiral nonracemic lactams 2 by using BH3.Me2S. A rationalization of the stereoselectivity is presented.
描述了对映体纯的顺式和反式2,3-二取代的哌啶4的合成。合成的关键步骤涉及通过使用BH3.Me2S立体选择性还原手性非外消旋内酰胺2。提出了立体选择性的合理化。
