This paper describes the development of a palladium‐catalyzed decarboxylative inter‐ and intramolecular condensation reaction of isoxazol‐5(4 H)‐ones with carbonyl compounds in the presence of PPh3, giving various 2‐azabuta‐1,3‐dienes or pyrroles in moderate to high yields.
本文描述了在PPh 3存在下异恶唑5(4 H)-one与羰基化合物的钯催化脱羧分子间和分子内缩合反应的发展 ,给出了各种2-azabuta-1,3-二烯或吡咯中等至高产。
