| 摘要 |
The invention relates to a process for preparing compounds of general formula: <CHEM> wherein R = Hydrogen, halogen, alkyl, nitro-group; said compounds, which are indicated hereinunder with the general term <<N-(dibenzyloxyphosphoryl)-cianamide>> 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. |
