- 1,2-Diol type polyol derivative compound and preparation method thereof and anti-microbial composition containing it
-
The present invention relates to a polyol derivative compound having a 1,2-diol structure represented by chemical formula 1, a method of preparing the same, and an anti-microbial composition containing the compound as an active ingredient. In the chemical formula: R1 is nitrogen (N) or sulfur (S); and R2 is OH or C2 alkyl. According to the present invention, the polyol derivative compound having a 1,2-diol structure represented by the chemical formula 1 exhibits excellent anti-microbial activities better than 1,2-hexanediol, which is known to have the best anti-microbial activity among polyols, thereby being effectively used as a preservative for a food product, a medicine, a cosmetic, and the like to prevent spoilage caused by microorganisms.COPYRIGHT KIPO 2019

- Modifications of DCDHF single molecule fluorophores to impart water solubility
-
A series of dicyanomethylenedihydrofuran (DCDHF) fluorophores with different hydrophilic groups were synthesized and their photophysical properties and water solubilities were measured. Significant water solubility was achieved without compromising desirable photophysical properties, permitting applications of these fluorophores in biological systems.

- The reaction of sulfamic acid derivatives with epoxides. 4. Hydrolysis of 3-chloro-2-hydroxypropylsulfamates
-
Under basic hydrolysis conditions 3-chloro-2-hydroxypropylsulfamates transform into 2,3-dihydroxypropylsulfamates. Acidic hydrolysis of the latter leads to 3-alkylaminopropane-1,2-diols.

- Carbonylation of β-Aminoethanols, Diols, and Diol Amines
-
Oxazolidinones are prepared from the palladium-catalyzed carbonylation of β-aminoethanols under mild conditions.With N-alkyl-substituted substrates, conditions for double carbon monoxide incorporation to give morpholinediones have been discovered.Cyclic carbonates can be prepared from the carbonylation of diols.The carbonylation of N-phenyl-1-aminopropane-2,3-diol can give either the carbonate or oxazolidinone as the major product depending on the reaction conditions.
