A three-step approach to 4-aryl-3-phenyl-3-pyrrolin-2-ones from a readily available tetramic acid is described. The introduction of different aryl groups to the 4-position of the ring system was accomplished utilizing Suzuki-Miyaura cross-coupling reactions of the corresponding tetramic acid triflate. This strategy was successfully employed in the first synthesis of the NH lactam analogue of rofecoxib.
本文描述了从易得的四甲基酸制备4-芳基-3-苯基-3-吡咯啉-2-酮的三步法。通过利用相应的四甲基酸三氟甲磺酸盐的铃木-宫浦交叉偶联反应,在环系统的4位上引入不同的芳基。该策略在罗非昔布的NH内酰胺类似物的首次合成中得到了成功应用。
