Photocatalytic Reductive Radical‐Polar Crossover for a Base‐Free Corey–Seebach Reaction

The styrene photocatalytic degradation reaction

In this study the aqueous styrene photocatalytic degradation reaction was evaluated using TiO 2 P-25 (Degussa) as catalyst. The experiments were accomplished in a batch reactor, with temperature control and catalyst in suspension. The radiation source was a 28 W UV lamp. Determinations of styrene concentrations were done by gas chromatography with a flame ionization detector (FID). Preliminary ...

Dual reaction channels for photocatalytic oxidation of phenylmethanol on anatase.

This work explores thoroughly the reaction network of the partial oxidation of phenylmethanol at the TiO(2)-solvent interface under photocatalytic conditions by using a first-principles continuum solvation method. We demonstrate that the photocatalytic oxidation of phenylmethanol has a complex reaction network with dual pathways. The dimer pathway dominates the mechanism under aerobic condition...

A Modified Orcinol Reaction for RNA Determination

&Mannich Reaction Iridium-Catalyzed Reductive Nitro-Mannich Cyclization

A new chemoselective reductive nitro-Mannich cyclization reaction sequence of nitroalkyl-tethered lactams has been developed. Relying on the rapid and chemoselective iridium(I)-catalyzed reduction of lactams to the corresponding enamine, subsequent nitro-Mannich cyclization of tethered nitroalkyl functionality provides direct access to important alkaloid natural-product-like structures in yield...

Reductive Deamination by Benzyne for Deoxy Sugar Synthesis Through a Domino Reaction

Benzyne was developed as a reducing agent in the key step of converting amino sugars and ketoses into deoxy sugars, which occur widely in natural products. Many deoxy sugars exhibit antibiotic and anticancer activities, and furthermore, they play essential biological roles. By treatment with CS2 and then Ac2O, amino sugars and ketoses were converted into the corresponding 1,3-thiazolidine-2-thi...
