✦ Synopsis

Asymmetric Hydrogenation of β-Ketophosphonates and β-Ketothiophosphonates with Chiral Ru(II) Catalysts.

-β-Hydroxyphosphonates (II) and β-hydroxythiophosphonates such as (IV) are synthesized by hydrogenation of the corresponding . beta.-keto compounds (I) and (III). The use of a chiral Ru(II) catalyst, prepared in situ, accomplishes excellent to good levels of enantioselectivity. -(GAUTIER, I.;
