and refractory multiple myeloma (MM). The structure features an isoindolinone core as well as a chiral α-amidoglutaramide moiety. An efficient kilogram-scale synthesis of the drug substance was required to enable clinical trials and development activities. The retrosynthetic disconnections, which proceed through acid-catalyzed glutarimide formation, lead to three starting materials, the syntheses of
Iberdomide ( 1 ·HCl) 是一种 cereblon E3 连接酶调节药物 (CELMoD),正在进行临床试验,用于治疗系统性红斑狼疮 (SLE) 和复发难治性多发性骨髓瘤 (MM)。该结构具有异吲哚酮核心和手性 α-酰胺戊二酰胺部分。需要有效的公斤级原料药合成才能进行临床试验和开发活动。通过酸催化戊二酰亚胺形成进行的逆合成断开产生三种起始材料,并讨论了它们的合成。通过双苄基氯的吗啉烷基化并有效选择性地去除不需要的次要双氨基杂质,形成苄基氯。达夫甲酰化用于制备水杨醛结构单元,并且通过创新地同时添加酸性和碱性溶液来分离该化合物。开发了L-异谷氨酰胺叔丁酯的短序列,以提供对 α-酰胺戊二酰胺的形成至关重要的手性胺。
