Dysoline, a novel chromone alkaloid isolated from Dysoxylum binectariferum, was reported to have selective cytotoxicity for HT1080 fibrosarcoma cells (IC50 of 0.21 μM). Given the scarcity of natural material, a concise synthesis of (+)-dysoline was developed, allowing for further biological evaluation. An enantioselective nucleophile-catalyzed aldol lactonization formed the piperidine ring with control
据报道,Dysoline是一种从Dysoxylum binectariferum分离出的新型
色酮生物碱,对HT1080纤维肉瘤细胞具有选择性的细胞毒性(IC 50为0.21μM)。考虑到天然物质的稀缺性,开发了(+)-
二氢吡啶的简明合成方法,可以进行进一步的
生物学评估。对映体选择性亲核试剂催化的醛醇内酯化形成
哌啶环,并控制相对和绝对立体
化学。使用Danheiser苯环,可实现具有完全区域选择性的C6-
色酮核心的构建。
