BMS-196085: A potent and selective full agonist of the human β3 adrenergic receptor
摘要:
A series of 4-hydroxy-3-methylsulfonanilido-1,2-diarylethylamines were prepared and evaluated for their human beta (3) adrenergic receptor agonist activity. SAR studies led to the identification of BMS-196085 (25), a potent beta (3) full agonist (K-i = 21 nM, 95% activation) with partial agonist (45%) activity at the beta (1) receptor. Based on its desirable in vitro and in vivo properties, BMS-196085 was chosen for clinical evaluation. (C) 2001 Elsevier Science Ltd. All rights reserved.

Substituted (1,2-diarylethyl)amides have been prepared and evaluated for their ability to inhibit microsomal acyl-CoA:cholesterol acyltransferase activity in vitro and to lower hepatic cholesteryl ester content in vivo in a cholesterol-fed hamster. Simple unsubstituted (diarylethyl)amides were potent inhibitors in vitro but showed poor activity in vivo. Introduction of polar groups at specific locations

A novel and easily accessible MN(SiMe3)2 (M = Li or Na)/Cs2CO3 co-catalyzed benzylation of in situ generated N-(trimethylsilyl) aldimines with toluene derivatives has been successfully developed. The catalyst exhibits high chemoselectivity for deprotonation of toluenes at the benzylic position. The utility of this system is exemplified by the one-pot synthesis of a diverse array of bioactive 1,2-diarylethylamines
已成功开发了一种新颖且易于使用的MN(SiMe 3)2(M = Li或Na)/ Cs 2 CO 3催化原位生成的N-(三甲基甲硅烷基)亚胺与甲苯衍生物的苄基化反应。该催化剂对苄基位置的甲苯去质子表现出高化学选择性。一锅合成具有优异效率和宽泛的官能团耐受性的各种生物活性1,2-二芳基乙胺的例子说明了该系统的实用性。

Use of the<i>N</i>-Formyliminium Ion Cyclization for the Synthesis of 3-Aryl-1,2,3,4-tetrahydroisoquinolines

Classical cyclization procedures for the synthesis of 3-arylisoquinolines are fraught with complications. Here, we present the application of an N-acyliminium cyclization to such target molecules. N-(1,2-diarylethyl)formamides 1, 4a-4d, and 4f were cyclized to the respective tetrahydroisoquinolines by using paraformaldehyde under mildly acidic conditions. Yields ranged from good to excellent. Cyclization of 4e was unsuccessful possibly because the presence of the 4-methoxyphenyl group leads to ionization of the formamido group.
Convenient Access to Primary Amines by Employing the Barbier-Type Reaction of <i>N</i>-(Trimethylsilyl)imines Derived from Aromatic and Aliphatic Aldehydes

A new versatile preparation of primary amines via benzylation of aromatic and aliphatic aldimines is described. Sonochemical and traditional methods for generation of the reactive intermediates are compared and contrasted. Competitive reactions were analyzed via free energy relationships to support the proposed alkylative mechanism.
