Regioselective [3+2]-annulation of hydrazonyl chlorides with 1,3-dicarbonyl compounds for assembling of polysubstituted pyrazoles

Org. Biomol. Chem., 2018, Accepted Manuscript DOI: 10.1039/C8OB02352B, CommunicationWenjun Li, Kun Liu, Xinye Shang, Yuyu Cheng, Xiaoyong Chang, Pengfei Li A facile approach to polysubstituted pyrazoles from hydrazonyl chlorides and 1,3-dicarbonyl compounds has been developed. In the presence of DMAP combined with Et3N, hydrazonyl chlorides reacted with N-phenyl-3-oxobutanamides smoothly to... The content of this RSS Feed (c) The Royal Society of Chemistry
