A facile synthesis of octahydro-pyrrolo[2,3-c]pyridine 1 using an intramolecular [3+2]-cycloaddition of an azomethine ylide as the key step and employing DW-therm heat-transfer fluid as a solvent is disclosed. Enantiomerically pure 1 was obtained either via a chromatographic separation of the diastereoisomers 12 and 13 resulting from the cycloaddition with a chiral appendage or by a classical resolution
公开了一种容易的合成八氢吡咯并[2,3- c ]吡啶1的方法,该方法使用偶氮甲叶立德的分子内[3 + 2]-环加成作为关键步骤,并使用DW-therm传热流体作为溶剂。对映体纯1是通过非对映异构体12和13的色谱分离而获得的,该非对映异构体12和13是通过手性附属物的环加成反应或通过消旋体19的经典拆分而获得的。
