UE Asymmetric synthesis

Course outline:

The principle of asymmetric synthesis is presented and illustrated by examples of asymmetric reduction of carbonyl, imines, alkenes, asymmetric oxydations, stereoselective alkylations, aldol reactions and stereoselective allylations. This asymmetric reaction toolbox set the basic knowledge to generate enantioenriched compounds, crucial for organic chemists. This course is also illustrated by the study of natural products asymmetric synthesis.
