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 Development of a robust immobilized organocatalyst for the redox-neutral mitsunobu reaction, published in 2021, which mentions a compound: 4221-99-2, Name is (S)-Butan-2-ol, Molecular C4H10O, Synthetic Route of C4H10O.
A polystyrene-supported version of the Denton catalyst for redox-neutral Mitsunobu reactions, (2-hydroxybenzyl)diphenylphosphine oxide, has been developed and used in catalytic inversion of enantiopure secondary alcs. (21 examples, up to 97% yield and 98% ee) with 2-nitrobenzoic and 2,4-dinitrobenzoic acids. The use in the reaction of alternative pronucleophiles has also been explored (8 successful and 3 unsuccessful examples). The functional resin shows high recyclability (10 cycles, 30 days operation) and can be re-activated by simple treatment with butylamine with further extension of its useful life.
Here is just a brief introduction to this compound(4221-99-2)Synthetic Route of C4H10O, more information about the compound((S)-Butan-2-ol) is in the article, you can click the link below.
