Efficient synthesis of 4-substituted pyrazole via microwave-promoted Suzuki cross-coupling reaction
摘要:
Pyrazoles and their derivatives are important heterocycles found in nature and present in numerous bioactive compounds. In contrast to 3 or 5-aryl pyrazole, the preparation of 4-aryl pyrazole is fairly rare. Utilizing microwave irradiation, the synthesis of 4-substituted-arylpyrazole via Suzuki cross-coupling has been developed with a wide range of substrates. The remarkable advantages of this method are mild reaction conditions, simple operation, high yield, and short reaction time. Product structures were identified by MS, H-1 NMR, C-13 NMR, and elemental analysis. (C) 2014 Qiong-You Wu and Guang-Fu Yang. Published by Elsevier B.V. on behalf of Chinese Chemical Society.
