Abstract
Description
Technical Field
[0001] This invention belongs to the field of synthetic pharmaceutical and chemical engineering, specifically relating to a β-triazole derivative, its synthesis method, and its application. Background Technology
[0002] Bifunctionalization of alkenes is a powerful and economical method for synthesizing complex and diverse compounds, attracting great interest from organic synthetic chemists. However, despite extensive efforts over the past few decades, catalytically achieving intermolecular bifunctionalization of alkenes remains a challenge due to the difficulty in controlling the chemical activation and regioselectivity of olefins. For example, in recent years, Pd or Ni catalysis has efficiently established 1,2-carbon amination bifunctionalization of alkenes via covalently linked directing groups. However, the need for directing groups significantly limits the chemical space available for its practical applications. Radical reactions for bifunctionalization of alkenes have subsequently been developed as another efficient strategy, constructing compounds with different complex structures through tandem radical relay strategies. In these cases, the secondary carbon-center radical generated can be captured by other radicals or oxidized to a carbocation, which is then captured by other nucleophiles. However, these methods remain limited to aromatic nitrogen heterocycles with broad bioactivity in the pharmaceutical and medical fields, such as 1,2,3-triazoles. Compared to aliphatic amines, aromatic nitrogen heterocycles are much less nucleophilic, more stable, and more difficult to generate the corresponding nitrogen-center radicals. To the best of our knowledge, there are no examples of 1,2-carbon triazoleization of olefins to construct β-triazole scaffolds by coupling aromatic nitrogen heterocyclic radicals with secondary carbon center radicals in radical relay reactions. Summary of the Invention
[0003] Here, the present invention proposes a first effective example of a strategy for generating β-triazole via a free radical relay reaction of alkyl compounds, aldehydes, disulfides, or diselenes with alkenes and N-sulfonyl-1,2,3-triazoles. Preliminary mechanistic studies indicate that the reaction proceeds via a similar S... N The tandem radical relay desulfonation process was carried out. The novel β-triazolone skeleton compounds obtained exhibited good selective inhibitory activity against osteosarcoma (OS) 143B, MNNG / HOS, and SJSA-1 cell lines, with some compounds showing inhibition rates as high as 99% at 10 μM. In contrast, control compounds without β-triazolyl or carbonyl groups showed no inhibitory activity against 143B cancer cells. These results demonstrate the broad application prospects of the β-triazolone skeleton in the pharmaceutical and medical fields.

An oxidant and additives are added to an organic solvent to react and obtain the β-triazole derivative shown in formula (I); the reaction process is shown in reaction formula (II).
[0012]
[0013] Wherein, 1 represents alkyl radicals, carbonyl radicals, thio radicals, and selenyl radicals generated by alkyl compounds / aldehydes / disulfides / diselenes under the action of oxidants and additives; R 1 R2 R 3 The definition is the same as in formula (I). R 4 It is methylsulfonyl or p-toluenesulfonyl.

[0027] Mechanism explanation: Alkyl compounds / aldehydes / disulfides / diselenes generate R under the action of oxidants and additives. 1 Free radical, R 1 The free radical then adds to the olefin to generate a secondary free radical 2i. This secondary free radical 2i then attacks the N2 position of the triazole, simultaneously initiating the departure of the triazole sulfonyl group, ultimately generating compound 4. Due to the steric hindrance effect of the triazole N1 position, the secondary free radical 2i will not attack the N1 position of the triazole to generate compound 4'.
