New synthetic methods were developed for the preparation of 2,3,6-trisubstituted 1-oxo-1,2-dihydroisoquinolines as CRTh2 antagonists. The isoquinolinone core could be constructed before the introduction of substitution groups or synthesized through a catalytic intramolecular cyclization reaction with desired substitution groups properly installed. These synthetic strategies have helped to accelerate
开发了新的合成方法来制备2,3,6-三取代的1-氧代-1,2-二氢异喹啉作为CRTh 2拮抗剂。异喹啉酮核心可以在引入取代基之前构建,或者通过具有适当安装的期望取代基的催化分子内环化反应合成。这些合成策略有助于加快该系列的SAR开发,并且在CRTh 2受体结合测定和CD11b生物标志物测定中均鉴定出有效的先导化合物。
