despite its significance, accessing such analogues via derivatization at a late stage remains a pivotal challenge. In an effort to mitigate this major limitation, we here present a strategy for the cobalt-catalysed late-stage C–H methylation of structurally complex drug molecules. Enabling broad applicability, the transformation relies on a boron-based methyl source and takes advantage of inherently present
The present invention relates to a process for preparing N-(1-alkenyl)carboxamides of the formula I, which comprises reacting a carboxamide of the formula II with an alkyne of the formula III in the presence of a catalyst selected from among carbonyl complexes, halides and oxides of rhenium, manganese, tungsten, molybdenum, chromium and iron.

The invention relates to the preparation and use of new aminopyrimidine derivatives as drug candidates in free form or in pharmaceutically acceptable salt form and formulations thereof for the modulation of a disorder or disease which is mediated by the activity of the PI3K enzymes. The invention also provides pharmaceutically acceptable compositions comprising such compounds and methods of using the compositions in the treatment of disorders or diseases, such as disorders of immunity and inflammation in which PI3K enzymes play a role in leukocyte function, and hyperproliferative disorders associated with PI3K activity, including but not restricted to leukemias and solid tumors, in mammals, especially humans.
