Chirality of thalidomide

WebThe rule of thumb is: chiral carbon centers are carbon atoms that are attached to four different substituents, that are placed at the corners of a tetrahedron. Chiral carbon atoms are also referred to as ‘stereogenic carbons’ or ‘asymmetrical carbon atoms’. Compound 1 has a chiral carbon center, because it is attached to four different ... WebThalidomide is racemic; while S-thalidomide is the bioactive form of the molecule, the individual enantiomers can racemize to each other due to the acidic hydrogen at the chiral centre, which is the carbon of the …
