An efficient and mild synthesis of imidazo[1,2-a]pyrimidine derivatives has been developed from readily available pyrimidyl arylamines or enamines through a hypervalent iodine-promoted intramolecular C–H bond cycloamination reaction. This protocol allows for the facile construction of biologically active bicyclic imidazo[1,2-a]pyrimidine skeletons as well as other imidazo[1,2-a]-type fused heterocycles
The present invention provides a compound of general Formula (I) having histone deacetylase (HDAC) and/or Cyclin-dependent kinase (CDK) inhibitory activity, a pharmaceutical composition comprising the compound, and a method useful to treat diseases using the compound.

A series of novelbenzamides derivatives was designed and synthesized as HDACinhibitors. Exploration of the structure–activity relationships resulted in compounds that are potent in vitro. In addition, the best compound 1a exhibited an acceptable pharmacokinetic profile with bioavailability in rat of 81% and could be considered as a candidate compound for further development.

A facile and environmental friendly protocol for the synthesis of N-bridged fused bicyclic compounds such as imidazo[1,2-a]pyridines, imidazo[1,2-a]pyrimidines, and imidazo[2,1-b]thiazole, from commercially available starting materials has been developed. The reaction proceeds via NBS mediated in situ formation of α-brominated intermediate of corresponding aromatic ketones, 1,3-diketones, β-keto esters
从N-桥联稠合双环化合物(如咪唑并[1,2- a ]吡啶,咪唑并[1,2- a ]嘧啶和咪唑并[2,1- b ]噻唑)合成的简便且环境友好的方案已经开发了可商购的原料。反应是通过NBS介导的原位形成相应芳族酮,1,3-二酮,β-酮酯的α-溴化中间体进行的,然后用适当的亲核试剂进行捕集,以提供在金属-金属化条件下高收率的这些通用的咪唑稠合双环杂环化合物。免费条件。
