The present invention provides fused ring heterocycles as kinase modulators, pharmaceutical compositions containing these modulators, and methods of using these modulators to treat diseases mediated by kinase activity.
Here we report an easy synthesis of bicyclic primary cyclopropylamines directly fromunsaturatednitriles. The described reaction involves Ti(II)-mediated intramolecular coupling of alkene and nitrile moieties.

A new methodology to afford α-amino nitriles through oxidative cyanomethylation of amines using nitromethane as the methylene source in the presence of Me3SiCN without the addition of an external oxidant was developed. A catalytic amount of AgCN and a stoichiometric amount of LiBF4 cooperatively promoted the transformation. A wide variety of the amines, including both aromatic compounds and aliphatic
开发了一种在 Me 3 SiCN存在下,在不添加外部氧化剂的情况下,使用硝基甲烷作为亚甲基源,通过胺的氧化氰甲基化来提供 α-氨基腈的新方法。催化量的AgCN和化学计量量的LiBF 4协同促进转化。多种胺,包括芳香族化合物和脂肪族胺,在氧化条件下不稳定,适用于该反应。
Electrochemically enabled decyanative C(sp<sup>3</sup>)–H oxygenation of <i>N</i>-cyanomethylamines to formamides
Selective oxygenation of C(sp3)–Hbonds adjacent to nitrogen atoms is a highly attractive strategy for synthesizing various formamide derivatives while preserving the substrate skeletons. Herein, an environmentally benign electrochemically enabled decyanative C(sp3)–H oxygenation of N-cyanomethylamines using H2O as a carbonyl oxygen atom source is described, leading to the synthesis of a large class
与氮原子相邻的C(sp 3 )–H 键的选择性氧化是合成各种甲酰胺衍生物同时保留底物骨架的极具吸引力的策略。在此,描述了使用 H 2 O 作为羰基氧原子源对N-氰基甲胺进行环境友好的电化学脱氰 C(sp 3 )–H 氧化反应,从而以良好至优异的收率合成了一大类甲酰胺,具有在无金属和无氧化剂的条件下具有广泛的底物范围。这种电化学技术突出了将N-甲酰基轻松结合到一些重要的生物活性分子中。
