Aryl extensions of thienopyrimidinones as fibroblast growth factor receptor 1 kinase inhibitors
摘要:
Optimization of thienopyrimidinone derivatives as FGFR1 kinase inhibitors is being pursued. The present results confirm predictions of computational modeling that an aryl substituent can be introduced at the 2-position in structure 3. The substituent is anticipated to project deeper into the binding site and provide opportunities for enhanced activity and selectivity. The most potent analog reported herein, 13, has a 4-hydroxyphenyl substituent and yields an IC(50) of 6 mu M for inhibition of phosphorylation by FGFR1 kinase. It was also found that the western anisole-containing substituent in 3 can be replaced by a propionic acid group with no loss in potency and with potentially significant gains in pharmacologically relevant properties.

1-methylcyclohexene derivatives with good yields and enantioselectivities. A novel chiral thiazolinyl iminoquinoline ligand and its cobalt complex were designed and synthesized to control the establishment of tertiary or quaternary carbon centers at a remote position. This protocol is operationally simple, and a model for the stereochemical outcome has been proposed.

for productive synthesis. Herein, we present straightforward conditions that provide access to a class of trans-arylcyclohexenes and demonstrate their utility in the formation of oxabicyclic ethers, which are otherwise inaccessible from the corresponding cis-cyclohexene. A key challenge to utilizing the incredible ca. 52 kcal/mol strain energy of trans-cyclohexene to drive synthesis was overcoming
虽然可以通过顺式环己烯的紫外线照射获得,但反式环己烯迄今为止一直是由好奇心驱动的研究,主要是由于其寿命短,直到最近才被用于生产合成。在这里,我们提出了直接的条件,提供了获得一类反式芳基环己烯并证明它们在形成氧杂双环醚中的效用,否则相应的顺式环己烯是无法获得的。利用令人难以置信的 ca 的关键挑战。用于驱动合成的反式环己烯的 52 kcal/mol 应变能克服了其短寿命的问题。在这里,我们表明在异构化之前通过底物和反应伙伴之间的氢键进行预组织是克服反式环己烯固有的短寿命的可行策略。
