Palladium-Catalyzed Tandem Allenyl and Aryl C–N Bond Formation: Efficient Access to N-Functionalized Multisubstituted Indoles
摘要:
An efficient palladium-catalyzed synthesis of N-functionalized multisubstituted indoles from easily accessible ortho-haloarylallenes and primary amines has been developed. A wide range of electronically and structurally varied nitrogen fragments could be introduced through this tandem C-N bond-forming process by tuning the reaction conditions.

result of re-optimization of lead compound 2, we identified novel compound 25a exhibiting potent inhibitory activity against HSL enzyme and cell with high selectivity for cholinesterases (AChE and BuChE). Reflecting its potent in vitro activity, compound 25a exhibited antilipolytic effect in rats at 1 mg/kg p.o., which indicated that this novel compound is the most potent orally active HSL inhibitor.
抑制HSL是治疗血脂异常的一种有前途的方法。作为重新优化铅化合物2的结果,我们确定了对HSL酶和对胆碱酯酶(AChE和BuChE)具有高选择性的细胞表现出有效抑制活性的新型化合物25a。化合物25a以1 mg / kg po的剂量在大鼠中表现出抗脂解作用,这表明该化合物是最有效的口服活性HSL抑制剂,反映了其强大的体外活性。此外,化合物25a没有显示出生物活化责任。
