A series of structurally novel P-chiral biaryl bisphosphorus ligands L1-L5 (BABIBOPs) are developed, providing high efficiency for the first time in palladium-catalyzed asymmetric hydrogenation of β-aryl and β-alkyl substituted β-keto esters. With the Pd-L3 (iPr-BABIBOP) catalyst, a series of chiral β-hydroxyl carboxylic esters are formed in excellent enantioselectivities (up to>99% ee) and yields at catalyst loading as low as 0.01 mol%.

First hand: The first example of a palladium-catalyzed asymmetric hydrogenation of α-acyloxy ketones (1) was accomplished to give the hydrogenated products 2 with by far the highest catalytic efficiency in up to quantitative conversions and excellent enantioselectivities. The hydrogenated products could serve as important intermediates for the preparation of many drug candidates. TFE=2,2,2-trifluoroethanol. Copyright
Synthesis, conformation and antiviral activity of nucleoside analogues with the (2-hydroxy-1-phenylethoxy)methyl glycone - A family of nucleoside analogues related to d4T and aciclovir
Ewing, David F.,Glacon, Virginie,Len, Christophe,Mackenzie, Grahame

A complete family of acyclic nucleoside analogues has been obtained by combining the (2-hydroxy-1-phenylethoxy)methyl glycone with the nucleoside bases adenine, guanine, cytosine, thymine and uracil. In each case both optical antipodes have been prepared
