Discovery of 4H-pyrazolo[1,5-a]pyrimidin-7-ones as potent inhibitors of hepatitis C virus polymerase
摘要:
A series of 4H-pyrazolo[1,5-a]pyrimidin-7-one derivatives was synthesized and evaluated for inhibitory activity against HCV NS5B RNA-dependent RNA polymerase. A number of these compounds exhibited potent activity in enzymatic assay. The synthesis and structure-activity relationship are also described. (C) 2009 Elsevier Ltd. All rights reserved.

A general three step synthesis of 3-alkyl furans, including Perillene and Dendrolasin, from alk-2-ynyl alcohols is described via radicalcyclisation of 2-bromo-1-ethoxyethyl alk-2-ynyl ethers to 2-ethoxy-4-alkylidene tetrahydrofurans.
