WebOct 26, 2024 · When one of the hydrogen atoms is changed to deuterium, this causes the carbon to become a chiral centre. We call this carbon a prochiral carbon. In the same way, the two hydrogens attached to the prochiral carbon is also known as prochiral hydrogens [3]. The prochiral hydrogens can be named pro-R of pro-S based on the resultant … Web5.4 Optical Activity. The two enantiomers are mirror images of each other. They are very alike and share many properties in common, such as the same b.p., m.p., density, color, and solubility. In fact, the pair of enantiomers have the same physical properties, except the way they interact with plane-polarized light.

WebJul 13, 2001 · Background: Thalidomide has a chiral centre, and the racemate of (R)- and (S)-thalidomide was introduced as a sedative drug in the late 1950s. In 1961, it was withdrawn due to teratogenicity and neuropathy. There is now a growing clinical interest in thalidomide due to its unique anti-inflammatory and immunomodulatory effects. …
