3-c]quinolin-4(5H)-ones were synthesized by utilizing 3-arylsydnones, ethyl 3-bromopropynoate, and 2-aminophenylboronic acid pinacol ester in presence of catalytic agent Pd(PPh3)4. This efficient one-pot synthesis methodology involved 1,3-dipolar cycloaddition, Suzuki coupling reaction, and intramolecular cyclization three sequence steps.
2-芳基吡唑并[3,4的两种区域异构体c ^ ]喹啉-4(5 ħ) -酮和2-芳基吡唑并[4,3- c ^ ]喹啉-4(5 ħ) -酮是通过利用3- arylsydnones合成在催化剂Pd(PPh 3)4存在下,3-溴丙酸乙酯和2-氨基苯基硼酸频哪醇酯。这种有效的一锅合成方法涉及1,3-偶极环加成,Suzuki偶联反应和分子内环化三个序列步骤。
