摘要:The invention provides methods for the synthesis of iron oxide nanoparticles and the particles obtainable by these methods. The particles can be used as tracer materials for magnetic particle imaging and for Magnetic Particle Spectroscopy (MPS). The method for the synthesis of these particles comprises the steps: (i) dissolving at least one water-soluble iron salt and at least one water-soluble stabilizer in water to form a reaction batch, (ii) adding at least one base to the reaction batch to yield a pH of 10 to 13, and (iii) exposing the reaction batch to a reaction temperature T R for a defined period of time DT, wherein T R ≥ 110°C, to obtain the iron oxide nanoparticles.

标题 :Synthesis of r-glucosides, sugar alcohols, reduced sugar alcohols, and furan derivatives of reduced sugar alcohols

摘要:Disclosed herein are methods for synthesizing 1,2,5,6-hexanetetrol (HTO), 1,6 hexanediol (HDO) and other reduced polyols from C5 and C6 sugar alcohols or R glycosides. The methods include contacting the sugar alcohol or R-glycoside with a copper catalyst, most desirably a Raney copper catalyst with hydrogen for a time, temperature and pressure sufficient to form reduced polyols having 2 to 3 fewer hydoxy groups than the starting material. When the starting compound is a C6 sugar alcohol such as sorbitol or R-glycoside of a C6 sugar such as methyl glucoside, the predominant product is HTO. The same catalyst can be used to further reduce the HTO to HDO.

摘要:Disclosed are a spirocyclic hydroxyindole imidazolinoxazepine compound and a synthesis method thereof, in particular being using a diazohydroxyindole and a dibenzoxazepine as reactants, and under the catalysis of iron (II) trifluoromethanesulfonate or p-toluenesulfonic acid monohydrate, synthesizing the product in a solvent. The method disclosed in the invention has the advantages of an easily obtainable raw material, mild reaction conditions, simple and convenient post-treatment, a wide range of available substrates, a high yield and a high diastereoselectivity; and the product obtained by the synthesis can be used for synthesizing the intermediates of drugs and pesticides.
