These compounds are useful in the synthesis of 4-aminopyrimidine-5-one derivatives that inhibit cyclin-dependent kinases, in particular cyclin-dependent kinase 4 (Cdk4). The 4-aminopyrimidine-5-one derivatives and their pharmaceutically acceptable salts have antiproliferative activity and are useful in the treatment or control of cancer, in particular solid tumors.
参考标题:Ruthenium-Catalyzed Site-Selective Intramolecular Silylation Of Primary C-H Bonds For Synthesis Of Sila-Heterocycles 作者:Huaquan Fang,Wenjun Hou,Guixia Liu,Zheng Huang |发布日期:2017.8.23 摘要:Medicinal Chemistry. Moreover, Organosilanes Are Valuable Synthetic Intermediates For Fine Chemicals And Materials. Transition Metal-Catalyzed C-H Silylation Has Become An Important Strategy For C-Si Bond Formations. However, Despite The Great Advances In Aromatic C(Sp2)-H Bond Silylations, Catalytic Methods For Aliphatic C(Sp3)-H Bond Silylations Are Relatively Rare. Here We Report A Pincer Ruthenium
