Catalyst-free visible-light-initiated oxidative coupling of aryldiazo sulfones with thiols leading to unsymmetrical sulfoxides in air

Green Chemistry, 2019
A facile visible-light-driven method has been developed to construct sulfoxides from aryldiazo sulfones and thiols in air under photocatalyst-free conditions.

Photochemical Deracemization of Chiral Sulfoxides Catalyzed by a Hydrogen-Bonding Xanthone Sensitizer

Synthesis, 2019
Several chiral sulfoxides with a lactam hydrogen-bonding site were prepared and their photochemical behavior was studied in the presence of xanthone and thioxanthone sensitizers.

Desulfurization of Diaryl(heteroaryl) Sulfoxides with Benzyne.

Organic Letters, 2019
Two benzyne-enabled desulfurization reactions have been demonstrated which convert diaryl sulfoxides and heteroaryl sulfoxides to biaryls and desulfurized heteroarenes, respectively. The reaction accessing biaryls tolerates a variety of functional groups,

Tyrosinase Catalyzes Asymmetric Sulfoxidation

Biochemistry, 2008
Mushroom tyrosinase was found to catalyze the oxidation of organic sulfides to sulfoxides in the presence of a catechol as cosubstrate, in a reaction which is unprecedented for this enzyme and resembles those performed by external monooxygenases. Only the oxy form of the enzyme is in fact capable of oxidizing the sulfide in a two-electron process ...

Chemoenzymatic Deracemization of Chiral Sulfoxides.

Angewandte Chemie, 2018
The highly enantioselective enzyme methionine sulfoxide reductase A was combined with an oxaziridine-type oxidant in a biphasic setup for the deracemization of chiral sulfoxides.
