Reactions with Chiral Non-Racemic Carbonyl Compounds 

Recently, by selection of the appropriate enantiomer of the chiral HWE reagent 31a, the concept of double asymmetric induction in an asymmetric carbonyl olefi-nation step has been applied in controlling the geometry of the alkenic intermediate 103 in the total synthesis of structurally complex macrolides [68, 69] vide infra).
