  Comparative molecular field analysis of fenoterol derivatives interacting with an agonist-stabilized form of the β2-adrenergic receptor

  摘要：

  The beta(2)-adrenergic receptor (beta(2)-AR) agonist [H-3]-(R,R')-methoxyfenoterol was employed as the marker ligand in displacement studies measuring the binding affinities (K-i values) of the stereoisomers of a series of 4'-methoxyfenoterol analogs in which the length of the alkyl substituent at alpha' position was varied from 0 to 3 carbon atoms. The binding affinities of the compounds were additionally determined using the inverse agonist [H-3]-CGP-12177 as the marker ligand and the ability of the compounds to stimulate cAMP accumulation, measured as EC50 values, were determined in HEK293 cells expressing the beta(2)-AR. The data indicate that the highest binding affinities and functional activities were produced by methyl and ethyl substituents at the alpha' position. The results also indicate that the K-i values obtained using [H-3]-(R,R')methoxyfenoterol as the marker ligand modeled the EC50 values obtained from cAMP stimulation better than the data obtained using [H-3]-CGP-12177 as the marker ligand. The data from this study was combined with data from previous studies and processed using the Comparative Molecular Field Analysis approach to produce a CoMFA model reflecting the binding to the beta(2)-AR conformation probed by [H-3]-(R,R')-4'-methoxyfenoterol. The CoMFA model of the agonist-stabilized beta(2)-AR suggests that the binding of the fenoterol analogs to an agonist-stabilized conformation of the beta(2)-AR is governed to a greater extend by steric effects than binding to the [H-3]-CGP-12177-stabilized conformation(s) in which electrostatic interactions play a more predominate role.

  通过对映分化H原子提取和立体保持自由基取代催化自由基C-H胺化的不对称诱导和对映发散

  摘要：

  对映选择性的控制仍然是自由基化学中的主要挑战。金属自由基催化 (MRC) 的出现为解决这一问题和其他突出问题提供了一种概念上的新策略。通过使用 D2 对称手性酰胺卟啉作为支持配体，基于 Co(II) 的 MRC 能够开发具有独特反应性和选择性特征的不对称自由基转化的新催化系统。在可微调腔环境的新一代 HuPhyrin 手性配体的支持下，共中心 d 自由基能够解决需要精确控制基本自由基过程的挑战性问题。正如氨磺酰叠氮化物的不对称 1,5-CH 胺化所展示的那样，其对映控制已被证明是困难的，通过调整桥长度和其他远程非手性元素明智地使用 HuPhyrin 配体允许以系统的方式控制不对称诱导的程度和意义。这一努力导致成功开发了新的基于 Co(II) 的催化系统，该系统对对映发散自由基 1,5-CH 胺化非常有效，产生具有优异对映选择性的应变 5 元环磺酰胺的两种对映异构体。详细的氘标记研究以及 DFT

  The hydroamination of vinylarenes with primary and secondary amines was studied with catalytic amounts as low as 2 mol-% of LiN(SiMe3)2/TMEDA. Reactions proceeded readily at 120 °C in the absence of solvent to give selective anti-Markovnikov addition. Slow addition was observed at 25 °C with either electron-deficient p-chlorostyrene or secondary cyclic amines such as pyrrolidine, piperidine, or morpholine

  found to be effective for the direct deaminative coupling of two primary amines to form secondary amines. The catalyst 1/L1 was highly chemoselective for promoting the coupling of two different primary amines to afford unsymmetric secondary amines. The analogous coupling of aniline with primary amines formed aryl-substituted secondary amines. The treatment of aniline-d7 with 4-methoxybenzylamine led to
