Chirotopic center
WebMar 1, 2024 · C3 is ACHIROTOPIC and stereogenic (pseudoasymmetric). Hence, the lower case "s" (C 3 -OH>C 2 -R>C 4 -S>H, which are the CIP priorities). Inversion of C3 leads to a new meso diastereomer (2R,3r,4S) that has the same chirotopicity and stereogenicity at the three centers as did the original triol. WebChirality is a useful concept in physical and life sciences, especially when applied to a molecular level. It derives from the Greek work cheir meaning “hand” because, like hands, the molecules and objects in general are not superposable with their mirror images [1].
