An efficient synthesis of 2-substituted indene-1,3(2H)-diones from stable and readily available 1-(2-halophenyl)-1,3-diones by employing phenyl formate as a CO source has been developed. The reaction occurred via palladium-catalyzed intramolecular carbonylative annulation using K3PO4 as a base and DMSO as a solvent at 95 °C. In this protocol, the reaction showed a broad substrate scope with good to
已经开发了通过使用甲酸苯酯作为CO源从稳定且容易获得的1-(2-卤代苯基)-1,3-二酮有效合成2-取代的茚-1,3(2 H)-二酮的方法。该反应通过在95°C下使用K 3 PO 4为碱和DMSO作为溶剂的钯催化的分子内羰基环化反应进行。在该方案中,反应显示出广泛的底物范围,具有良好或优异的产率。
Syntheses of quinazolinones from 2-iodobenzamides and enaminones via copper-catalyzed domino reactions
N-Substituted 2-iodobenzamides and enaminones undergo cascade transformations to achieve quinazolinones via a copper-catalyzed Ullmann-type coupling, a Michael addition and a retro-Mannich reaction. A unique stereochemical feature of this domino process was that Z-enaminones reacted without external ligands, whereas E-enaminones required the assistance of ligands.
Benzamide ring-substituted, quinine-derived ebselen analogue is synthesized which exists in selenol form upon addition of PhSH. It catalyses oxidation of PhSH with H2O2 faster (103-fold) than ebselen.
