A concise and environmentally friendly protocol was developed for the synthesis of 6-phenylbenzo[h]quinolines. 6-Phenylbenzo[h]quinolines were obtained in good yields via irradiation of (E)-2-phenyl-3-styrylpyridines with a 254 nm UV light (64 W) in EtOH under an argon atmosphere in the presence of TFA. The reaction is a dehydrogenative annulation reaction that proceeds through 6π-electrocyclization
开发了一种用于合成 6-苯基苯并[ h ]喹啉的简明且环保的方案。在存在 TFA 的情况下,在 EtOH 中用 254 nm 紫外光 (64 W)照射 ( E )-2-苯基-3-苯乙烯基吡啶,以良好的收率获得6-苯基苯并[ h ]喹啉。该反应是一个脱氢环化反应,通过 6π-电环化、[1,5]-H 位移、1,3-烯胺互变异构化和氢分子的消除得到 6-苯基苯并[ h ]喹啉。所描述的协议不仅避免了过渡金属催化剂和氧化剂的使用, 而且还具有原子效率高和反应条件温和的优点。

2,3- and 2,5-Dibromopyridines reacted with arylboronic acids, catalyzed by Pd(OAc)(2)/PPh3 in the presence of K2CO3 in CH3CN/MeOH (2:1) at 50 degrees C for 24 h, to afford 2-aiylpyridines in good to high yields, while 2,4-dibromopyridine reacted with arylboronic acid pinacol esters, catalyzed by Pd(OAc)(2)/PPh3 in the presence of KOH in CH3CN at 70 degrees C for 24 h, to afford 2-arylpyridines in good to high yields. To expand this methodology, a 170-HSD1 inhibitor was synthesized in good yield. (C) 2013 Elsevier Ltd. All rights reserved.
