Description: 

This course provides an advanced knowledge and understanding of stereochemistry of organic compounds, principles of asymmetric synthesis and methods.

Educational Goals:

-to develop a knowledge base of organic stereochemistry and methods for achieving stereoselectivity.

-to master an understanding of reactivity principles associated with stereoselective synthesis.

-to gain the ability to propose stereoselective method for a given chiral product.

-to develop fundamental critical thinking skills and analogous reasoning.
