3,4-Substituted-5-aminopyrazoles and 4-substituted-2-aminothiazoles are frequently used intermediates in medicinal chemistry and drug discovery projects. We report an expedient flexible synthesis of 3,4-substituted-5-aminopyrazoles (35 examples), based on palladium-mediated α-arylation of β-ketonitriles with aryl bromides. A library of 4-substituted-2-aminothiazoles (21 examples) was assembled by a
Asymmetric synthesis of the four diastereoisomers of a novel non-steroidal farnesoid X receptor (FXR) agonist: Role of the chirality on the biological activity
designed for the preparation of the four possible diastereoisomers of 3,6-dimethyl-1-(2-methylphenyl)-4-(4-phenoxyphenyl)-4,8-dihydro-1H-pyrazolo[3,4-e][1,4]thiazepin-7-one, a non-steroidal FXR agonist, we recently discovered following a virtual screening approach. The results obtained from an AlphaScreen assay clearly demonstrated that only the isomer endowed with 4R,6S absolute configuration is responsible
设计了一种不对称合成策略,用于制备3,6-二甲基-1-(2-甲基苯基)-4-(4-苯氧基苯基)-4,8-二氢-1H-吡唑并[ 4]的四种可能的非对映异构体。我们最近通过虚拟筛选方法发现了4- e ] [1,4] thiazepin-7-one(一种非甾体FXR激动剂)。从AlphaScreen分析获得的结果清楚地表明,只有具有4 R,6 S绝对构型的异构体才是生物活性的原因。使用计算模型研究对这些对映体纯配体采用的不同推定结合模式进行了深入研究,证实了FXR对此类分子的对映选择性。
