An ortho-selective ammonium chloride salt-catalyzed direct C–H monohalogenation of phenols and 1,1′-bi-2-naphthol (BINOL) with 1,3-dichloro-5,5-dimethylhydantoin (DCDMH) as the chlorinating agent has been developed. The catalyst loading was low (down to 0.01 mol %) and the reaction conditions were very mild. A wide range of substrates including BINOLs were compatible with this catalytic protocol. Chlorinated

Para C-H borylation (CHB) of tetraalkylammonium sulfates and sulfamates have been achieved using bipyridne-ligated Ir boryl catalysts. Selectivities can be modulated both by the length of the alkyl groups in the tetraalkylammonium cations and the substituents on the bipyridine ligands. Ion-pairing, where the alkyl groups of the cation shield the meta C-H bonds in the conteranions, is proposed to account
四烷基硫酸铵和氨基磺酸盐的对位 CH 硼化 (CHB) 已使用联吡啶连接的 Ir boryl 催化剂实现。选择性可以通过四烷基铵阳离子中烷基的长度和联吡啶配体上的取代基来调节。离子对,其中阳离子的烷基屏蔽了对位离子中的间位 CH 键,被认为是对位选择性的原因。4,4'-二甲氧基-2,2'-联吡啶配体具有优异的选择性。

BTK and PI3Kδ are kinases responsible for B-cell signal transduction, and inhibitors of these enzymes have demonstrated clinical benefit in certain types of lymphoma. Simultaneous inhibition of these pathways could result in more robust responses or overcome resistance as observed in single agent use. We report a series of novel compounds that have low nanomolar potency against both BTK and PI3Kδ as
