Cu-Catalyzed Synthesis of Benzoxazole with Phenol and Cyclic Oxime

A Cu-catalyzed straightforward synthesis of benzoxazoles from free phenols and cyclic oxime esters is reported. The mild reaction conditions tolerate various electron-withdrawing and electron-donating functional groups on both substrates, affording benzoxazoles in moderate to good yields. With this protocol, large-scale syntheses of Ezutromid and Flunoxaprofe in one or two steps are demonstrated. A catalytic mechanism, which includes Cu-catalyzed amination via inner-sphere electron transfer and consequent annulation, is proposed.

Sulfoxide and sulfone compounds, as well as selective synthesis method and application thereof

The invention discloses a method for selectively synthesizing a sulfoxide compound shown as a formula (II) and a sulfone compound shown as a formula (III). In a reaction solvent, thioether (I) is usedas a reaction raw material and oxygen as an oxidation reagent, under the catalytic action of visible light and a photosensitive reagent; under the assistance of an additive, when a large-polarity proton-containing additive such as an acid and an alcohol or a solvent or an additive with excellent electron donating ability is used, a sulfoxide compound (II) is selectively generated; and when a small-polarity aprotic additive or a solvent is used, a sulfone compound (III) is selectively generated. The synthesis method has the advantages of easily available and cheap raw materials, simple reaction operation, mild reaction conditions, high yield and excellent functional group tolerance. According to the invention, synthesis and modification of some medicines are realized, and an efficient method for selectively constructing sulfoxide and sulfone compounds is provided for medicinal chemistry research.

Selective Late-Stage Oxygenation of Sulfides with Ground-State Oxygen by Uranyl Photocatalysis

Oxygenation is a fundamental transformation in synthesis. Herein, we describe the selective late-stage oxygenation of sulfur-containing complex molecules with ground-state oxygen under ambient conditions. The high oxidation potential of the active uranyl cation (UO22+) enabled the efficient synthesis of sulfones. The ligand-to-metal charge transfer process (LMCT) from O 2p to U 5f within the O=U=O group, which generates a UV center and an oxygen radical, is assumed to be affected by the solvent and additives, and can be tuned to promote selective sulfoxidation. This tunable strategy enabled the batch synthesis of 32 pharmaceuticals and analogues by late-stage oxygenation in an atom- and step-efficient manner.
