A multicomponent synthesis of triazinane diones

An efficient, one-pot synthetic protocol toward triazinane diones, a rather Unexplored class of heterocyclic scaffolds combining phosphonates, nitrites, aldehydes, and isocyanates is described. The optimization of the reaction, synthesis of a small library of different triazinane diones, as well as alternative routes toward the triazinane dione scaffold are discussed.
