Formula (I) ((Ia) and (Ib)) compounds wherein (i) X1 is N and X2 is S, (ii) X1 is CR7 and X2 is S, (iii) X1 is N and X2 is NR2, or (iv) X1 is CR7 and X2 is O, including stereoisomers, tautomers, metabolites and pharmaceutically acceptable salts thereof, are useful for inhibiting the delta isoform of PI3K, and for treating disorders mediated by lipid kinases such as inflammation, immunological, and cancer. Methods of using compounds of Formula (I) for in vitro, in situ, and in vivo diagnosis, prevention or treatment of such disorders in mammalian cells, or associated pathological conditions, are disclosed.
We report herein an efficient synthesis of diversely polysubstituted imidazo[1,2-a]pyridines, a family of aza-heterocycles endowed with numerous biological properties, through a sequence involving two consecutive palladium-catalyzedcross-couplingreactions. First, we demonstrated that a Hirao coupling occurred straightforwardly in high yields at positions 3, 5, and 6 of imidazopyridine derivatives
我们在这里报告了通过涉及两个连续的钯催化的交叉偶联反应的序列,有效合成了多种取代的咪唑并[1,2- a ]吡啶,这是一种具有许多生物学特性的氮杂杂环家族。首先,我们证明了Hirao偶联在咪唑并吡啶衍生物的位置3、5和6处以高收率直接发生,从而获得了广泛的取代膦酸酯,次膦酸酯和氧化膦。在第二步中,发现磷酰咪唑并吡啶与芳基卤化物的直接CH-芳基化是有效且完全选择性的,这取决于空间位阻,导致中等至高收率的3-芳基取代的咪唑并吡啶。
