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 Short synthesis of (R)- and (S)-4-amino-3-hydroxybutyric acid (GABOB), published in 2005-03-07, which mentions a compound: 90866-33-4, Name is (R)-Ethyl 4-chloro-3-hydroxybutanoate, Molecular C6H11ClO3, Reference of (R)-Ethyl 4-chloro-3-hydroxybutanoate.
A simple and stereospecific synthesis of both (R)- and (S)-GABOB has been developed. The synthetic approach involves the conversion, through organoselenium intermediates, of com. available Et (R)- and (S)-4-chloro-3-hydroxybutyrate into a protected 1,2-amino alc. with retention of the original configuration.
This literature about this compound(90866-33-4)Reference of (R)-Ethyl 4-chloro-3-hydroxybutanoatehas given us a lot of inspiration, and I hope that the research on this compound((R)-Ethyl 4-chloro-3-hydroxybutanoate) can be further advanced. Maybe we can get more compounds in a similar way.
