A concise synthesis of chiral indanes as α 1A adrenoceptor partial agonists
摘要:
The synthesis of a series of chiral indanes with reported am partial agonist activity is outlined, applying a rhodium catalysed cyclisation for template construction. This method was extended to the asymmetric synthesis of lead compound PF-03774076 (1) which was prepared on >20 g scale in seven steps. Highlights include Rh-mediated cyclocarbonylation and an asymmetric alkene hydrogenation. (C) 2015 Elsevier Ltd. All rights reserved.
Palladium-catalyzed alkene-directed cross-coupling of aryliodide with another aryl halide through C-H arylation opens a unique avenue for unsymmetrical biaryl-derived molecules. However, homo-coupling of aryliodides often erodes the overall synthetic efficiency. Reported herein is a highly chemoselective Pd0 -catalyzed alkyne-directed cross-coupling of aryliodides with bromophenols, which was subsequently

A series of cyclic C-glycosides were synthesized using the palladium-catalyzed stereoretentive intramolecular glycosylation of aryl iodides by employing a bulkyphosphine ligand. A variety of functional groups are tolerated in the reaction, and enantioenriched anomeric nucleophiles could be coupled without erosion of optical purity. This study offers a unified method to access both cis- and trans-fused
通过使用庞大的膦配体,使用钯催化的芳基碘的立体保留分子内糖基化合成了一系列环状C-糖苷。反应中允许使用多种官能团,并且对映体富集的异头亲核试剂可以在不损害光学纯度的情况下偶联。这项研究提供了一种通过利用 Stille 反应的立体保持性来访问顺式和反式稠环的统一方法。此外,分子间和分子内交叉偶联的竞争实验显示,二次 KIE 分别为 1.43 和 0.81,表明在过渡态存在截然不同的空间拥塞。
