Two palladium‐catalysed amination protocols are deployed in the desymmetrisation of the complex dimeric alkaloid meso‐chimonanthine. The power of these transformations is showcased in an efficient formal and total synthesis of the natural products hodgkinsine and hodgkinsine B, respectively.
二钯催化胺化协议,部署在复杂的二聚生物碱的去对称中观chimonanthine。这些转化的力量分别在天然产物何杰金素和何杰金素B的高效正式和全面合成中得到了展示。
