Definitions
- Triazole is an important five-membered nitrogen heterocyclic compound, involved in a wide range of industrial applications, such as agrochemicals, corrosion inhibitors, dyes, fluorescent brighteners, and biologically active agents.
- Azide functional groups are extremely important and widely used in organic synthesis. However, because these compounds have high energy, they have great safety hazards during synthesis, storage, and transportation, which makes synthesis and use difficult.
- the methods for synthesizing azides currently available to civilization are very limited. Most of the alkyl, acyl, and sulfonyl azides are obtained by nucleophilic substitution reaction, using NaN 3 to replace the leaving functional group in a polar solvent. This method requires For separation and purification, the synthesis efficiency is not high, resulting in the need for cumbersome post-processing for further activity screening.
- step (b0) m different amines respectively located in m reaction chambers are used to react with FSO 2 N 3 to obtain different RN 3 .
- the solvent is an ether solvent, a mixed solvent of a sulfoxide solvent and water, or a mixed solvent of an ether solvent, a nitrile solvent and water.
- the step (1) includes the steps:
- heterocyclic group means a group consisting of 2 to 14 carbon atoms and 1 to 6 heteroatoms selected from nitrogen, phosphorus, oxygen and sulfur Stable 3- to 20-membered non-aromatic cyclic group.
- the heterocyclic group may be a monocyclic, bicyclic, tricyclic or more ring system, which may include a fused ring system, a bridged ring system or a spiro ring system; in the heterocyclic group
- the nitrogen, carbon, or sulfur atoms of may be optionally oxidized; the nitrogen atom may be optionally quaternized; and the heterocyclic group may be partially or fully saturated.
- the heterocyclic group can be connected to the rest of the molecule via a carbon atom or a heteroatom and through a single bond.
- one or more rings may be aryl or heteroaryl as defined below, provided that the point of attachment to the rest of the molecule is a non-aromatic ring atom.
- a CuAAC-based synthesis reaction is used to realize chemical connection between two molecules, thereby constructing a compound library with high throughput.
- the azide compound as a 1,3-dipolarizing reagent can also be prepared by reacting an amine fragment with a fluorosulfonyl azide.
- An exemplary reaction formula is as follows:
- 1128 different primary amine compounds (including primary alkyl amines, primary aryl amines, and primary aromatic heterocyclic amines) were prepared into a solution with a concentration of about 100 mM, the solvent was dimethyl sulfoxide, and the volume was about 1 ml , And stored in a 1.2 ml 96-well microplate.
- 1128 corresponding azide compounds were obtained by this method.
- the 1128 azide compound solutions were distributed in 12 96-well microplates (microplate numbers 1-7 and 10-14).
- the 96 separately stored primary amines mentioned in Example 2 (part of the primary amines have poor solubility) were reacted by the same method in this example to obtain 96 soluble azide compound solutions and transferred to a new piece of 96-well microtiter plate (see the 8th plate of the azide library for details).
- a compound library containing a total of 1224 azide solutions with different structures was built.
