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 First total synthesis of macrosphelides C and F, published in 2001-04-09, which mentions a compound: 53562-86-0, Name is (S)-Methyl 3-hydroxybutanoate, Molecular C5H10O3, Category: piperazines.
Macrosphelides C and F were synthesized by lactonization of 14-oxo seco acids at the O(10)-C(11) bond followed by reduction and Mitsunobu inversion of the resulting hydroxyl group. The seco acids were prepared from the corresponding furans by furan ring-opening with NBS followed by further oxidation of the 4-oxo-2-alkenals with NaClO2.
Although many compounds look similar to this compound(53562-86-0)Category: piperazines, numerous studies have shown that this compound(SMILES:C[C@H](O)CC(OC)=O), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
