(±)-chlorizidine A has been achieved in 10 steps. Pd-catalyzed decarboxylative coupling and late-stage oxidation were utilized to construct the 5H-pyrrolo[2,1-a]isoindol-5-one scaffold. Samarium(II) iodide mediated Reformatsky reaction and intramolecular Mitsunobu reactions were efficiently applied for the synthesis of the 2,3-dihydropyrrolizine ring system. Chlorizidine A is highly prone to degradation; hence, methyl-protected
甲基保护的(±)-氯联苯胺A的第一个全合成已通过10个步骤完成。钯催化的脱羧偶联和后期氧化被用来构建5 H-吡咯并[2,1 - a ] isoindol-5-one支架。碘化Sa(II)介导的Reformatsky反应和分子内Mitsunobu反应有效地用于合成2,3-二氢吡咯烷嗪环系统。氯唑烷A极易降解;因此,制备了甲基保护的(±)-氯联苯胺A。
