Efficient and simple synthesis of 3-aryl-1H-pyrazoles
摘要:
Efficient preparation of 3-aryl-1H-pyrazoles by reaction of 1-protected-5-(4,4.5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)1H-pyrazoles with (het)aryl halides is described. The choice of THP protecting. group is discussed. (c) 2006 Elsevier Ltd. All rights reserved.
