Is a chiral center the same as a stereocenter

WebC1-substitution. A stereocenter at C1 is a typical feature in natural THβCs and establishment of this stereocenter has received plenty of attention. C1-Substituted THβCs have a wide variety of pharmacological properties, including PDE5-inhibitory [2], antimalarial [3–9], antiviral [10–13] and antitumor [14–17] activities. WebEach chiral center is a stereogenic center in that the interchange of two ligands results in a stereoisomer. Since each chiral center can only be R or S and the configuration of a particular chiral center can be changed merely by exchanging any two valences, the remaining stereoisomers of A can now be generated easily by switching valences of one …
