In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis and evaluation of anthelmintic and cytotoxic properties of [2,5′]bis-1,3-azole analogs of bengazoles, published in 2009-09-30, which mentions a compound: 118994-89-1, Name is Ethyl oxazole-5-carboxylate, Molecular C6H7NO3, Synthetic Route of C6H7NO3.
Using different heterocycle formation methodologies (Deoxo-Fluor, DAST, POCl3, TosMIC), [2,5′]bis-1,3-azoles were prepared as stable analogs of bengazoles, a family of potent anthelmintic marine natural products. The cytotoxic activity of these heterocycles and their precursors on HCT-15 cells and the effect on the L4 larvae of Nippostrongylus brasiliensis were evaluated.
