substrate scope including various linear or cyclic saturated ketones and aldehydes. The protocol is ligand‐free, and molecular oxygen is used as the sole clean oxidant in the reaction. Due to mild reaction conditions, good functional group compatibility, and versatile utilities of enones and enals, the method can be applied in the late‐stage synthesis of natural products, pharmaceuticals and fine chemicals

afford the corresponding 2‐alkylbenzoic acids in moderate to excellent yields. This C−H alkylation process is generally applicable to diversely substituted electron‐rich and electron‐deficient benzoic acids, along with α,β‐unsaturated olefins including unprotected acrylic acid. The widely available carboxylate directing group can be removed or utilized for further derivatization. Mechanistic investigations
在催化性[RuCl 2(p- cym)] 2的存在下,以Li 3 PO 4为碱,苯甲酸与水中的烯烃反应,以中等至极好的收率得到相应的2-烷基苯甲酸。这种CH烷基化过程通常适用于各种取代的富电子和缺电子的苯甲酸,以及包括未保护丙烯酸的α,β-不饱和烯烃。广泛使用的羧酸酯导向基团可以被除去或用于进一步的衍生化。机理研究表明,转化是通过钌循环中间体进行的。

A compound of general formula (I) or pharmaceutically acceptable prodrugs, salts, hydrates, solvates, crystal forms or diastereomers thereof is described. A method of treating a hyperproliferation-related disease state or disorder in a subject using a compound of formula (I) is also described.
to plasmalemmal β2-adrenoceptors causing cAMP accumulation are widely used as bronchodilators in chronic respiratory diseases. Here, we designed and synthesized a group of 8-hydroxyquinolin-2(1H)-oneanalogues and studied their β2-agonistic activities with a cellular cAMP assay. Compounds B05 and C08 were identified as potent (EC50 < 20 pM) and selective β2-agonists among the compounds tested. They
