asymmetric center造句

• The possibilities continue to multiply as there are more asymmetric centers in a molecule.
• The carbon atom would be tetrahedral as usual and would have four different substituents on it, thus it is an asymmetric center.
• "In certain non-catalytic reactions that diastereomer will predominate, which could be formed by the approach of the entering group from the least hindered side when the rotational conformation of the C-C bond is such that the double bond is flanked by the two least bulky groups attached to the adjacent asymmetric center ."
• Clinically, thalidomide has always been used as a interconversed " in vivo " due to the acidic chiral hydrogen in the asymmetric center ( shown, for the EM-12 analog, in Figure 3 ), so the plan to administer a purified single enantiomer to avoid the teratogenic effects will most likely be in vain.
