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 Single Enantiomer, Chiral Donor-Acceptor Metal Complexes from Bisoxazoline Pseudoracemates, published in 2006-06-22, which mentions a compound: 132098-59-0, Name is Bis((S)-4-phenyl-4,5-dihydrooxazol-2-yl)methane, Molecular C19H18N2O2, Related Products of 132098-59-0.
Single enantiomer, chiral donor-acceptor metal complexes (I) were synthesized via the self-discriminating zinc(II) complexation of a pseudoracemic mixture of donor/acceptor-substituted bisoxazoline derivatives
