- Dihydroxy pyrimidine compound and use thereof
-
The invention provides a dihydroxy pyrimidine compound, its structural general formula is: Wherein R1 In order to contain the substituent of the aryl, heterocyclic or containing substituent is C1 - C6 alkyl; R2 Is C1 - C6 alkyl, C1 - C6 alkyl aryl, C1 - C6 alkyl heterocyclic group or a hydrogen atom; x, y each is between 0 - 6 is any natural number. The invention also provides a two-hydroxy pyrimidine compounds in the preparation of anti-influenza virus in the application. The present invention provides a dihydroxy pyrimidine compounds to the influenza virus activity has better inhibition, can remarkably reduce the toxicity of the influenza virus, and cytotoxicity is relatively low, thus can such compounds for the preparation of anti-influenza virus drugs.

- Synthesis of Nitriles from Aldehydes with Elongation of the Molecule with Two Carbon Atoms
-
A new protocol for the synthesis of nitriles from carbonyl compounds with elongation of the molecule with two carbon atoms was developed. It involves a reaction of ethyl cyanoacetate with different aldehydes in the presence of iron pentacarbonyl as a redu

- Formal reductive addition of acetonitrile to aldehydes and ketones
-
An efficient and highly productive rhodium-catalyzed method for the synthesis of nitriles employing aldehydes or ketones, methyl cyanoacetate, water and carbon monoxide as starting materials has been developed. Simple rhodium chloride without any ligands can be used. The fine tuning of the substrate can lead to the activity higher than 5000 TON.

- Reductive Transformations of Carbonyl Compounds Catalyzed by Rhodium Supported on a Carbon Matrix by using Carbon Monoxide as a Deoxygenative Agent
-
An efficient method for the rhodium on carbon matrix catalyzed preparation of secondary and tertiary amines, cyanoesters, and nitriles through the reductive amination/alkylation of carbonyl compounds was developed, including a convenient procedure for the tandem formal reductive addition of acetonitrile to aldehydes. The catalyst could be reused, and at least three consecutive reaction cycles were performed with comparable efficiency. The method was shown to be compatible with functional groups prone to reduction by hydrogen and complex hydrides. Beyond the matrix: An efficient method for the rhodium on carbon matrix catalyzed preparation of secondary and tertiary amines, cyanoesters, and nitriles through the reductive amination/alkylation of carbonyl compounds is developed, including a convenient procedure for the tandem formal reductive addition of acetonitrile to aldehydes. TON=turnover number.

- Monoalkylation of acetonitrile by primary alcohols catalyzed by iridium complexes
-
The monoalkylation of acetonitrile by primary alcohols was achieved in a one-pot sequence in the presence of iridium catalysts. A diversity of nitriles has been obtained from aryl- and alkyl-methanols in excellent yield.
