Synthesis and optimization of substituted furo[2,3-d]-pyrimidin-4-amines and 7H-pyrrolo[2,3-d]pyrimidin-4-amines as ACK1 inhibitors
摘要:
Two classes of ACK1 inhibitors, 4,5,6-trisubstituted furo[2,3-d]pyrimidin4-amines and 4,5,6-trisubstituted 7H-pyrrolo[2,3-d]pyrimidin-4-amines, were discovered and evaluated as ACK1 inhibitors. Further structural refinement led to the identification of potent and selective dithiolane inhibitor 37. (C) 2012 Published by Elsevier Ltd.

bond-forming dearomatization of pyridines and pyridazines at room temperature. The catalytic reaction operates directly on free heterocycles and generates the nucleophiles in situ, eliminating the need for stoichiometric preactivation of either reaction partner; further, it is one of very few methods available for the enantioselective 1,4-dearomatization of heteroarenes. Combining the dearomatization with
我们展示了手性氢化铜 (CuH) 配合物在室温下催化吡啶和哒嗪的 CC 键形成脱芳构化。催化反应直接作用于游离杂环并原位生成亲核试剂,无需对任一反应伙伴进行化学计量预活化;此外,它是可用于杂芳烃的对映选择性 1,4-脱芳构化的极少数方法之一。将脱芳构化与简便的衍生化步骤相结合,可以一锅法合成富含对映体的吡啶和哌啶。
