The discovery of the JAK-STAT pathway was a landmark in cell biology. The identification of these pathways has changed the landscape of treatment of rheumatoid arthritis and other autoimmune diseases. The two first (unselective) JAK inhibitors have recently been approved by the US FDA for the treatment of myelofibrosis and rheumatoid arthritis and many(More)
The elaboration of the first organophosphorus-catalyzed diaza-Wittig reaction is reported. This catalytic reaction is applied to the synthesis of substituted pyridazine and phthalazine derivatives bearing electron-withdrawing groups with good to excellent yields from substrates containing a diazo functionality as the starting material and a phospholene(More)
The first synthesis of novel fused pyridazines has been realized starting from 1,3-diketones involving a Diaza-Wittig reaction as a key step. A convenient strategy was elaborated to access versatile pyridazine derivatives allowing the variation of substituents at position 6 of the heterocyclic ring. In a first part, pyridazines bearing an ester group were(More)
