The palladium-catalyzed reaction of the ethyl 2-acetyl-4-pentynoate tosylhydrazone with aryl iodides in the presence of K2CO3 and catalytic amounts of a palladium complex affords 1,2,3,5-substituted pyrroles in satisfactory yield.
在 K2CO3 和一定量的钯络合物催化下,2-乙酰基-4-戊炔酸乙酯甲苯腙与芳基碘化物发生钯催化反应,生成 1,2,3,5 取代的吡咯,产率令人满意。
