摘要

A convenient general method is reported for the synthesis of α-aryl substituted ethylphosphonic acids and esters by hydrogenation of α-aryl substituted ethenylphosphonic acids and esters. Racemic α-arylethylphosphonic acids and esters were prepared in 70– 88% yield under palladium-assisted transfer hydrogenation conditions using ammonium formate. Asymmetric hydrogenation of α-arylethenylphosphonic acids using chiral Ru (II) ...
