Investigation of the reaction of α-thioamides, α-esters and α-nitriles with NBS and NCS is described. The scope of this stereoselective oxidative transformation to the β-haloacrylamides, β-acrylates and β-acrylonitriles has been determined. A mechanistic rationale to explain the observed differences in reactivity between the amide, ester and nitrile series is proposed.
Discovery of (−)-6-[2-[4-(3-fluorophenyl)-4-hydroxy-1-piperidinyl]-1-hydroxyethyl]-3,4-dihydro-2(1H)-quinolinone—A potent NR2B-selective N-methyl d-aspartate (NMDA) antagonist for the treatment of pain
(-)-6-[2-[4-(3-Fluorophenyl)-4-hydroxy-l-piperidinyl]-l-hyd roxyethyl]-3,4-di hydro-2(1H)-quinolin one was identified as an orally active NR2B-subunit selective N-methyl-D-aspartate (NMDA) receptor antagonist. It has very high selectivity for NR2B subunits containing NMDA receptors versus the HERG-channel inhibition (therapeutic index = 4200 vs NR2B binding IC50). This compound has improved pharmacokinetic properties compared to the prototype CP-101,606. (c) 2007 Elsevier Ltd. All rights reserved.
(-)-6-[2-[4-(3-氟苯基)-4-羟基-1-哌啶基]-1-羟乙基]-3,4-二氢-2(1H)-喹啉酮被鉴定为一种口服活性的、选择性作用于NR2B亚基的N-甲基-D-天冬氨酸(NMDA)受体拮抗剂。该化合物对含有NR2B亚基的NMDA受体显示出极高的选择性,相对于HERG通道抑制作用(治疗指数=4200 vs NR2B结合IC50)。与原型化合物CP-101,606相比,该化合物具有改进的药代动力学特性。(c)2007 Elsevier Ltd. 保留所有权利。

The new Scorpio type olefin metathesis catalysts with very high affinity to silica gel are reported. After completion of the reaction, those complexes can be efficiently separated from reaction product by direct filtration of reaction mixture through a short pad of silica gel. Products obtained by this methodology are contaminated with low amounts of residual ruthenium. Especially, catalyst (H2IPr)(Cl)(2)Ru=C(H)(C6H4OR) (5b, R=CH(Me)(C(O)N(Me)OMe) exhibited very high activity and could be easily recovered and reused. Additionally, this catalyst was found to be effective already at 0.1-0.5 mol % and showed good compatibility with environmentally benign solvents. (C) 2013 Elsevier Ltd. All rights reserved.
