Chiral cyclopentadienylruthenium sulfoxide catalysts for asymmetric redox bicycloisomerization
Beilstein Journal of Organic Chemistry, 2016 A full account of our efforts toward an asymmetric redox bicycloisomerization reaction is presented in this article. Cyclopentadienylruthenium (CpRu) complexes containing tethered chiral sulfoxides were synthesized via an oxidative [3 + 2] cycloaddition ...

Sulfoxide-Controlled SN2‘ Displacements between Cyanocuprates and Epoxy Vinyl Sulfoxides1
, 2016 Two short and convergent routes have been devised for the preparation of enantiomerically pure acyclic epoxy vinyl sulfoxides. These substrates undergo highly regio- and stereoselective SN2‘ displacements with lithium cyanocuprates to give α‘-alkylated ...

Thiol-free chemoenzymatic synthesis of β-ketosulfides
Beilstein Journal of Organic Chemistry, 2019 A preparation of β-ketosulfides avoiding the use of thiols is described. The combination of a multicomponent reaction and a lipase-catalysed hydrolysis has been developed in order to obtain high chemical diversity employing a single sulfur donor.

Synthesis and Evaluation of Novel Benzofuran Derivatives as Selective SIRT2 Inhibitors
Molecules, 2017 A series of benzofuran derivatives were designed and synthesized, and their inhibitory activites were measured against the SIRT1–3. The enzymatic assay showed that all the compounds showed certain anti-SIRT2 activity and selective over SIRT1 and SIRT3 ...

Inhibition of methionine sulfoxide reduction by dimethyl sulfoxide
BMB Reports, 2009 Dimethyl sulfoxide (DMSO) is widely used in chemistry and biology as a solvent and as a cryoprotectant. It is also used as a pharmaceutical agent for the treatment of interstitial cystitis and rheumatoid arthritis. Previous reports described DMSO as being reduced by methionine-S-sulfoxide reductase (MsrA).
