A highly efficient, flexible, and convergent route to cis-2,3,6-trisubstituted piperidines has been developed employing the Sharpless asymmetric aminohydroxylation and stereoselective reductive amination by catalytic hydrogenation as the key steps. Its usage is illustrated by the short synthesis of the piperidine-3-ol alkaloid, (−)-deoxocassine.
已经开发出一种高效,灵活和收敛的顺式-2,3,6-三取代哌啶路线,采用Sharpless不对称氨基羟基化反应和通过催化氢化的立体选择性还原胺化作为关键步骤。哌啶-3-醇生物碱(-)-脱氧叶卡因的短合成说明了其用法。
