标题:Electrochemical synthesis of niacin and other N-heterocyclic compounds
发明人：TOOMEY JR JOSEPH E
权利人:REILLY IND INC
摘要:An electrochemical oxidation of a pi-deficient N-heterocyclic precursor compound having an oxidizable organic group attached by a carbon-to-carbon linkage. This precursor compound is at least sparingly water soluble. The preferred electro-oxidation is conducted at an effective anode and in a medium which consists essentially of water, carboxylic acid, and the precursor compound. Preferred are electro-oxidations of substituted pyridine and quinoline bases and a particularly preferred aspect provides a convenient electrochemical synthesis of niacin from 3-methylpyridine.

标题 :Process for preparing n-(dibenzyloxyphosphoryl)-cyanamide and processes using said compounds as intermediate for the synthesis of phosphagen substances
摘要:The invention relates to a process for preparing compounds of general formula: wherein R = Hydrogen, halogen, alkyl, nitro-group; said compounds, which are indicated hereinunder with the general term <> are useful as intermediates in the synthesis of phosphagen compounds such as phosphocreatine, phosphocreatinine and similar compounds. Such process is characterized in that dibenzyloxyphosphoryl chloride is reacted with cyanamide, N-(dibenzyloxyphosphoryl)-cyanamide being produced; this latter can react with substances provided with a primary or secondary amine function, to give the corresponding guanidinoderivatives; e.g., with a sarcosine derivative to give N-(dibenzyloxyphosphoryl)-creatine or N-(dibenzyloxyphosphoryl)-creatinine.
