Brønsted acid catalyzed asymmetric reduction of ketones and acyl silanes using chiral anti-pentane-2,4-diol.

Org. Lett. 12(10) , 2294-7, (2010)

Ketones and acyl silanes were reduced to the corresponding alcohols by a simple procedure employing anti-1,3-diol and a catalytic amount (5 mol %) of 2,4-dinitrobenzenesulfonic acid in benzene at refl...

Highly efficient synthesis of enantiopure diacetylated C(2)-symmetric diols by ruthenium- and enzyme-catalyzed dynamic kinetic asymmetric transformation (DYKAT).

Chemistry 12 , 6053, (2006)

Highly efficient synthesis of enantiopure diacetates of 2,4-pentanediol and 2,5-hexanediol starting from commercially available mixtures of the diols (dl/meso approximately 1:1) has been realized by c...

2,4-Pentanediolate as an alkoxide/diketonate "hybrid" ligand and the formation of aluminum and zirconium derivatives.

Inorg. Chem. 50(23) , 12126-32, (2011)

When 2,4-pentanediol (2,4-H(2)pd) is deprotonated, the resulting dianion (2,4-pd) serves as a type of "hybrid" ligand, i.e., an alkoxide that possesses structural features of a β-diketonate. 2,4-Penta...
