Paragraph 0018-0021, (2022/01/10)
The present invention belongs to the field of indole synthesis technology, in order to solve the current synthesis of indole and its derivatives with ethylene glycol as raw material, the conditions are relatively harsh, the structure of the main catalyst is complex, expensive and other issues, providing a synthesis method of indole derivatives. Pt/Al2O3 catalyst supportingPt/Al2O3was prepared by impregnation with acidicAl2O3as the support, using aniline compounds, ethylene glycol, and the preparedPt/Al2O3 Catalyst for catalytic reaction, control reaction temperature of 190 °C, reaction 24h, after the end of the reaction, first add water to stir evenly, and then with dichloromethane for extraction, organic phase by rotational distillation to remove the solvent, and then with petroleum ether, ethyl acetate as the eluent column chromatography separation, you can obtain the target product. A broad spectrum of the Catalytic System ofPt/Al2O3Supported Catalysts with Good Catalytic Effect inthe Glycol Aniline Reaction was studied, and the substrate range of substituted aniline was mainly expanded.

The oxidative esterification of various aldehydes with alcohols could be achieved by a heterogeneous iron(iii) catalyst supported on a ring-like POM inorganic ligand under mild conditions, affording the corresponding esters, including several drug molecules and natural products, in high yields. ESI-MS and control experiments demonstrated that POM-FeV(O) was the active catalytic species and the plausible mechanism was presented. More importantly, the 6th run of the iron catalyst recycles shows only a slight decrease in the yield.

Antibacterial compound and its salt
-
Paragraph 0031-0035, (2017/10/06)
The invention provides a compound of a formula I or a pharmaceutically acceptable salt, a hydrate or a crystal form thereof. An acyl group is connected with the fourth, fifth or sixth-site carbon atom of indolyl. Researches find that the compound provided by the invention has certain antibacterial activity, and can be used as a potential antibacterial drug or daily chemical. Beyond all expectations, a compound 4c is extremely similar to compounds 4a and 4b in structure, but the antibacterial activity of the compound 4c is obviously better than that of the other two compounds; the antibacterial activity of the compound 4c against staphylococcus aureus is significantly better than the antibacterial activity of the compound 4c against escherichia coli, which illustrates that the compound 4c is more sensitive to the staphylococcus aureus; and if being used for antibiosis, the compound 4c can more easily inhibit particular species (such as staphylococcus aureus) in a targeted way, so that the unnecessary drug resistance caused by other bacteria is avoided.
A double-indole hydrazone compound and use thereof
-
Paragraph 0036; 0039-0040, (2017/10/06)
The invention provides a bisindole acylhydrazone compound shown as the formula I or salt, hydrate or crystals, accepted in the pharmacy, of the bisindole acylhydrazone compound. According to the bisindole acylhydrazone compound, R does not exist or is selected from alkylene of C1-5. The bisindole acylhydrazone compound has a certain antibacterial activity, and can serve as potential antibiotics or a daily chemical product. What is beyond the expectation is that compounds 4e-4h and compounds 4a-4c are quite similar in structure, the antibacterial activity of the compounds 4e-4h and the antibacterial activity of the compounds 4a-4c are obviously better than that of other compounds, particularly, the activity of the compound 4h is best and is remarkably better than that of compounds 4e-4g. The formula I is shown in the specification.

Ye, Ying,Suo, Yourui,Yang, Fang,Yang, Yongjing,Han, Lijuan
, p. 296 - 299 (2015/06/02)
Indole acylhydrazones were synthesised in high yields under microwave irradiation By using indole carboxylic acid and 1,4-benzenedialdehyde as starting materials. Their structures were characterised by 1H NMR, IR, MS spectra and elemental analysis. Selective recognition properties of these receptors have been investigated by UV-Vis spectra titration indicating that these receptors can form 1:1 supramolecular complexes with malic acid, tartaric acid, ascorbic acid and tryptophan.
