Oxazolone derivative 3a was utilized as a versatile precursor for the construction of new heterocyclic scaffolds containing imidazole, oxazine, triazine, and triazole rings (compounds 20, 21, 23, and 24, respectively). Furthermore, 4‐aminohippuric acid (2b) was used in the synthesis of various new oxazolone derivatives (13–19) by utilizing of its amino group in several transformations followed by heterocyclization
