A one-pot approach to 4,5-dihydropyrazoles from ketones, arylacetylenes, and hydrazines
摘要:
An efficient and straightforward one-pot strategy for the synthesis of 4,5-dihydropyrazole derivatives from ketones, arylacetylenes, and hydrazines in the presence of (KOBu)-Bu-t/DMSO is described. This strategy provides a flexible and rapid route to polysubstituted 4,5-dihydropyrazoles. (C) 2014 Elsevier Ltd. All rights reserved.
