aldehyde with the D-lyxo configuration is a versatile key intermediate to functionally and stereochemically diversified piperidines. It allowed the synthesis of natural 3,4,5-trihydroxypiperidines and new analogs through a double reductive amination strategy and the synthesis of novel 2-cyanotrihydroxypiperidines through a highly regio- and diastereoselective Strecker reaction.
具有 D-lyxo 构型的 D-甘露糖衍生的醛是功能和立体化学多样化的哌啶的通用关键中间体。它允许通过双还原胺化策略合成天然 3,4,5-三羟基哌啶和新类似物,并通过高度区域和非对映选择性 Strecker 反应合成新型 2-氰基三羟基哌啶。
