carbazoles, benzothiophenes and benzofurans are important motifs in the pharmaceutical industry. Herein we report a novel, regioselective method to introduce alkyl substituents into positionortho of nitro groups by the addition of a Grignardreagent followed by subsequent oxidation with DDQ.
Disclosed herein are aminopyrimidine compounds that inhibit FGFR and methods of treating diseases and/or conditions (e.g., cancer) with the aminopyrimidine compounds disclosed herein.
for their in vitro antiproliferativeactivities. We found that this series of compounds is particularly interesting in the development of new inhibitors of DYRK1A and CLK1 kinases. The most effective compounds toward these two kinase families are the 6- and 7-bromo derivatives 30, 33, and 34 that showed more than 45-fold selectivity toward DYRK1A/CLK1 kinases over the other kinases tested.
