Six in one blow: Total syntheses of all the amathaspiramide alkaloids have been accomplished. Rapid construction of the diazaspiro[3.3]nonane core combined with regio‐ and diastereoselective reduction of the cyclic imide moiety with DIBAL established the route to the common structural motif. The late‐stage reduction of the lactam to an imine functionality mediated by Schwartz's reagent was the key
六合一打击:已完成所有阿马他螺旋酰胺生物碱的全部合成。diazaspiro [3.3]壬烷核心的快速构建,再加上DIBAL的环酰亚胺部分的区域和非对映选择性还原,为常见的结构基序建立了途径。由Schwartz试剂介导的将内酰胺后期还原为亚胺功能是简化合成的关键。
