Various heterocycles containing phosphorus and nitrogen are easily synthesized from readily available H-phosphinate building blocks. Aminomethylation of these H-phosphinates is followed by in situ cyclization through substitution or cross-coupling to produce novel heterocycles in moderate to good yields.
5- And 6-membered ring phostams are functionalized at nitrogen and carbon through the use of metal-catalyzed reactions, such as copper-catalyzed cross-coupling and palladium-catalyzed reductive Heck reaction. Different approaches are compared for the heterocyclization step and the introduction of the substituents.
