Lack of selectivity between anesthetic stereoisomers for an inhibitory site which is located on a membrane protein.

P W Tas et al.

Biochimica et biophysica acta, 1026(1), 40-42 (1990-07-09)

Lack of selectivity towards anesthetic stereoisomers is one of the few criteria available for the identification of an anesthetic target site. Until now this criterion has not been tested for anesthetics that directly interact with sensitive membrane proteins which are

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

Eric J Bierschenk et al.

Inorganic chemistry, 50(23), 12126-12132 (2011-11-08)

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-Pentanediol reacts with Al(O-s-Bu)(3) and Zr(O-i-Pr)(4) to form chelated multinuclear complexes. The aluminum-containing product

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

Jun-Ichi Matsuo et al.

Organic letters, 12(10), 2294-2297 (2010-04-23)

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 reflux. Asymmetric induction reached up to >99% ee when a chiral

Theoretical insight into stereoselective reaction mechanisms of 2,4-pentanediol-tethered ketene-olefin [2 + 2] cycloaddition.

Katsumasa Kamiya et al.

The journal of physical chemistry. A, 116(4), 1168-1175 (2012-01-10)

We report ab initio molecular dynamics calculations based on density functional theory performed on an intramolecular [2 + 2] cycloaddition between ketene and olefin linked with a 2,4-pentanediol (PD) tether. We find that the encounter of the ketene and olefin

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

Belén Martín-Matute et al.

Chemistry (Weinheim an der Bergstrasse, Germany), 12(23), 6053-6061 (2006-06-27)

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 combining a fast ruthenium-catalyzed epimerization with an enzymatic transesterification. The in situ coupling of these
