- Synthesis method of saccharide-containing polymeric monomer N-(2-D-glucanoamidoethyl)methacrylamide
-
The invention provides a synthesis method of a saccharide-containing polymeric monomer N-(2-D-glucanoamidoethyl)methacrylamide, and relates to the field of synthesis of organic high molecular materials. The synthesis method comprises the following specific steps: dissolving D-gluconolactone in anhydrous methanol to form a solution, and then sequentially adding intermediates AEMA, triethylamine andhydroquinone into the solution, the ratio of the three components is AEMA: D-glucose lactone: triethylamine = 18: 11: 36, mixing and oscillating for 5 hours to obtain a milky white solution, concentrating through rotary evaporation, repeatedly washing by using anhydrous dichloromethane, performing centrifugal filtration, and performing vacuum drying to obtain a final sample, wherein the ratio ofamounts of substance of the D-gluconolactone and the anhydrous methanol 0.0113:1, and the ratio of amounts of substance of the AEMA, the D-gluconolactone and the triethylamine is 18:11:36. By the synthesis method provided by the invention, the saccharide-containing polymeric monomer which is economical and applicable, can stably exist in a strong acid hydrolysate and can be specifically bonded with and adsorb protein is prepared.

- Salen-Based Covalent Organic Framework
-
The Salen unit represents one of the most important ligands in coordination chemistry. We report herein the first example of a Salen-based covalent organic framework (COF), in which both the construction of the COF structure and the functionalization with Salen moieties have been realized in a single step. Due to its structural uniqueness, the obtained COF material, Salen-COF, possesses high crystallinity and excellent stability. Based on this, a series of metallo-Salen-based COFs were prepared via metalation for further applications.

- ORGANOPHOSPHORUS COMPOUNDS AS POTENTIAL FUNGICIDES. PART I. N-(ω-GUANIDINOALKYL)AMINOALKANEPHOSPHONIC ACIDS AND THEIR AMINOPHOSPHONIC PRECURSORS: PREPARATION, NMR SPECTROSCOPY, AND FAST ATOM BOMBARDMENT MASS SPECTROMETRY
-
N-(ω-Aminoalkyl)- and N-(ω-guanidinoalkyl)-aminoalkanephosphonic acids have been prepared from α,ω-diaminoalkanes by reaction with chloromethanephosphonic acid (or an ester of a halogenoalkanephosphonic acid), followed by treatment with S-methylisothiouronium chloride.Ethylene diamine yielded 1-phosphonomethyl-2-iminoimidazolidine.A number of 1:1 salts of the α,ω-diamines and chloromethanephosphonic acid are also reported.Doubly charged zwitterionic structures are assigned to both ω-amino and ω-guanidino compounds on the basis of 31P and 13C nmr data.Thus the addition of an excess of acid (D2SO4) causes the 31P chemical shift to move to higher field, from ca. 8 to 14 ppm, whilst 1JPC increases from ca. 130 to 150 Hz.The 1H and 13C chemical shifts. of the terminal methylene groups in the polymethylene chain are unaffected by acidification.Fast atom bombardment mass spectrometry gives rise to characteristic + ions, frequently as the base peak, and to fragmentations involving the loss of phosphorous acid, or the formation of ions resulting from carbon-nitrogen or carbon-carbon cleavage.The compounds show activity against a number of fungal pathogens and other microbial organisms.Key words: Organophosphorus; fungicides; guanidinophosphonic acids; aminophosphonic acids; NMR spectroscopy; FAB mass spectrometry.
