In a modification of the Friedlander reaction, 2-aminobenzyl alcohol is oxidatively cyclized with a variety of ketones to yield substituted quinolines. Of all the ruthenium catalysts that were tested for this reaction, the second-generation Grubbs' catalyst gives the highest quinoline yield, in combination with KOtBu as a base. The presence of a hydrogen acceptor is required to regenerate the catalyst
在 Friedlander 反应的改进中,2-氨基苯甲醇与各种酮氧化环化以产生取代的喹啉。在为该反应测试的所有钌催化剂中,第二代 Grubbs 催化剂与 KOtBu 作为碱结合时,喹啉产率最高。需要氢受体的存在来再生催化剂。还讨论了反应机理,结果表明可能有两种不同的途径生成喹啉。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
