Synthesis method of alpha-carbonyl sulfonate and catalyst used in synthesis method

The invention provides a nitrogen and carbon co-doped Nb2O5 catalyst for synthesizing alpha carbonyl sulfonate, a preparation method of the nitrogen and carbon co-doped Nb2O5 catalyst, and a synthesizing method of the alpha carbonyl sulfonate by using the catalyst under the driving of visible light. Based on the total weight of the catalyst, the content of nitrogen is 0.01 wt%-1wt%; the content of the carbon is 0.01 wt% to 1.5 wt%. The catalyst provided by the invention is used for preparing alpha-carbonyl sulfonate through olefin aerobic oxidation, the reaction condition is mild, oxygen is used as an oxidant, and other oxidants are not needed. All the raw materials of the catalyst are rich in resource and low in price, and the catalyst can be recycled without inactivation and is very stable to air, water and heat.

Regioselective three-component synthesis of 1,2-diarylindoles from cyclohexanones, α-hydroxyketones and anilines under transition-metal-free conditions

A facile method for the one-pot synthesis of 1,2-diarylindoles under transition-metal-free conditions is described. Cyclohexanones were used as the aryl sources via the dehydrogenative aromatization process. One C-C and two C-N bonds were selectively formed via a domino reaction. This protocol provides a convenient approach for the construction of valuable bioactive 1,2-diarylindoles from readily available cyclohexanones, α-hydroxyketones and anilines.

Synthesis of α-sulfonyloxyketones via iodobenzene diacetate (PIDA)-mediated oxysulfonyloxylation of alkynes with sulfonic acids

A simple yet powerful method to synthesize a variety of α-sulfonyloxyketones has been developed. This novel method can be applied for the direct oxysulfonyloxylation of alkynes with sulfonic acids to access a variety of α-sulfonyloxyketones. Compared to the reported methods for the application of PIDA, this study expands its application scope and uses it not only as the oxidant but also as the carrier of O to form the carbonyl group in the products. In addition, under the established conditions, this methodology not only exhibits a broad substrate scope but also demonstrates exclusive regioselectivity with substrates of 1,2-disubstituted internal alkynes.
