A novel method for the synthesis of trisubstituted oxazoles via a one-pot oxazole synthesis/Suzuki-Miyaura coupling sequence has been developed. One-pot formation of 5-(triazinyloxy)oxazoles using carboxylic acids, amino acids and a dehydrative condensing reagent, DMT-MM, followed by Ni-catalyzed Suzuki-Miyaura coupling with boronic acids provided the corresponding 2,4,5-trisubstituted oxazoles in
已经开发了一种通过单锅恶唑合成/ Suzuki-Miyaura偶联序列合成三取代恶唑的新方法。使用羧酸,氨基酸和脱水缩合剂DMT-MM一锅法形成5-(三嗪氧基)恶唑,然后与硼酸进行镍催化的铃木-宫浦偶联,提供相应的2,4,5-三取代恶唑丰产。
