DIASTEREOISOMERS

• Diastereoisomers are not mirror image isomers. They are essentially like any other pair of isomers (e.g., constitutional isomers) in that they have distinct chemical and physical properties. Since they have the same functional groups, however, they are usually rather similar to one another in their reactions and properties.
• Two diastereoisomers can usually be separated from one another by , e.g., recrystallization, since they have different solubilities.
• Although their chemical properties(reactions) are similar, the two diastereoisomers will typically react at different rates.
