- Introduction

- Syllabus

- Name Reaction List- How to best approach these

- Problem Sets- How these work

- Model Sets- not necessary but really will help a lot. Framework molecular model kits or Orbit sets will do.

Nomenclature:

Enantiomers: Stereoisomers which are not superimposable upon their mirror images.arg

Diastereomers: Stereoisomers which are not related by mirror images.

Switch one center to generate a diastereomer. If n = # of chiral centers, then there are 2n/2 sets of diastereomers.

Meso Compounds: These molecules have chiral centers however, they also contain a plane of symmetry and therefore do not rotate polarized light. These are achiral molecules.

Designation of face on a molecule:

Types of Reactions:

1)Stereospecific Reactions: stereoisomerically different starting materials give stereoisomerically different products under the same reaction conditions.

2)Stereoselective Reactions: A reaction in which a single reactant could generate two or more stereoisomeric products but one is formed preferentially.

3)Regioselective Reaction: A reaction in which a single reactant could generate two or more positional isomers but one is formed preferentially.

Syn and Anti Designations:

Syn - Bonds are made and broken on the same face of a plane of a double bond.

Anti - Bonds are made and broken on opposite sides of a plane of a double bond.
