asymmetric reduction of α,β-unsaturatedketones (enones) having a pyridyl ring affords the corresponding optically active α-substituted ketones (α-chiral ketones) with excellent stereoselectivity. The position of the heteroatom, as well as the bulk of the α-substituent, plays an important role in governing the stereoselectivity in the reduction of a carboncarbon doublebond.
