Base-catalyzed cyclization of monofluorodienynes: a new route to substituted fluorobenzene derivatives
摘要:
The Sonogashira reaction of 1-bromo-1-fluoro-4-phenyl-1,3-butadienes and terminal alkynes, followed by cyclization in the presence of DABCO in refluxing NMP affords fluorinated benzene derivatives site-specifically in good yields. (c) 2006 Elsevier Ltd. All rights reserved.
The present invention relates to novel hepcidin antagonists of formula (I), pharmaceutical compositions comprising them and the use thereof as medicaments, in particular for treatment of disorders in iron metabolism, such as, in particular, iron deficiency diseases and anaemias, in particular anaemias in connection with chronic inflammatory diseases (ACD: anaemia of chronic disease and AI: anaemia of inflammation).
