• Highly Linear Selective Cobalt-Catalyzed Addition of Aryl Imines to Styrenes: Reversing Intrinsic Regioselectivity by Ligand Elaboration
  作者：Wengang Xu、Naohiko Yoshikai

  DOI：10.1002/anie.201408028

  日期：2014.12.15

  Highly linear selective, imine‐directed hydroarylation of styrene has been achieved with cobalt‐based catalytic systems featuring bis(2,4‐dimethoxyphenyl)(phenyl)phosphine and either 2‐methoxypyridine or DBU as a ligand and a Lewis base additive, respectively, thus affording a variety of 1,2‐diarylethanes (bibenzyls) in good yields under mild reaction conditions. The triarylphosphine controls the regioselectivity

  使用基于双（2,4-二甲氧基苯基）（苯基）膦和2-甲氧基吡啶或DBU分别作为配体和Lewis碱添加剂的钴基催化体系，可以实现苯乙烯的高度线性选择性，亚胺定向的氢芳基化反应，因此，在温和的反应条件下，可以提供高收率的各种1,2-二芳基乙烷（联苄）。三芳基膦控制区域选择性，而路易斯碱则显着加速反应。配体筛选和氘标记研究提供了有关配体和路易斯碱在关键的CC还原消除步骤中的作用的暗示。

  It is intended to provide a drug which is efficacious against pathological conditions relating to arginine-vasopressin V1b receptor. More particularly speaking, it is intended to provide a drug which has a therapeutic or preventive effect on depression, anxiety, Alzheimer's disease, Parkinson's disease, Huntington's chorea, eating disorders, hypertension, digestive diseases, drug addiction, epilepsy, brain infarction, brain ischemia, brain edema, head injury, inflammation, immune diseases, alopecia and so on. As the results of intensive studies, a novel 1,3-dihydro-2H-indol-2-one compound and a pyrrolidin-2-one compound fused with a heteroaromatic ring, which are highly selective antagonists of arginine-vasopressin V1b receptor, have high metabolic stabilities and show favorable brain penetration and high plasma concentrations, are found, thereby achieving the above objective.

• Fluorescent phosphoinositide 3-kinase inhibitors suitable for monitoring of intracellular distribution
  作者：Donghee Kim、Hyunseung Lee、Hwiseok Jun、Soon-Sun Hong、Sungwoo Hong

  The monitoring of the drug behavior and distribution in biological system can provide information whether drug reaches its desired target, and a biological rationale for the design of new therapeutics. We have developed a family of potent fluorescent PI3K alpha inhibitors in which part of the fluorophore was engineered to be a pharmacophore capable of inhibiting PI3K alpha. These xanthine derivatives are characterized by a donor-acceptor molecular structure, and changes in the electronic properties of the two variation points at R-1 and R-2 give rise to notable bathochromic shifts in the lambda(em), (abs) and increase the value of Phi(F). Further, we illustrated the use of E2 (PI3K alpha/IC50 = 0.068 mu M, T47D cell viability: IC50 = 0.9 mu M) to block cancer cell proliferation and to monitor its subcellular localization by fluorescence microscopy.

• Synthesis of Halogenated Anilines by Treatment of <i>N</i>,<i>N</i>-Dialkylaniline <i>N</i>-Oxides with Thionyl Halides

  The special reactivity of N,N-dialkylaniline N-oxides allows practical and convenient access to electron-rich aryl halides. A complementary pair of reaction protocols allow for the selective para-bromination or ortho-chlorination of N,N-dialkylanilines in up to 69% isolated yield. The generation of a diverse array of halogenated anilines is made possible by a temporary oxidation level increase of N
