专利号:EP-0150883-B1 优先权日:1984-02-02 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.

The process of preparing the intermediate of aminoimidazole carboxylate comprises subjecting a compound of formula I-2 and a formate as the reactants to a first-step reaction in a benzene solvent and at a temperature of −5° C.−5° C., with the addition of a solution of sodium alkoxide in such a way that the temperature of the reaction solution is not higher than 5° C., to obtain the intermediate of aminoimidazole carboxylate or a mixture comprising a compound of formula I-3, i.e., the intermediate of aminoimidazole carboxylate. By using a sodium alkoxide reagent, as a comparatively safe alternative to NaH and potassium tert-butoxide which are prone to cause fire hazards or explosions and are not suitable for use in large-scale production, the process of the present application can ensure smooth progression of the reaction to the product and effectively improve the overall safety of the reaction without noticeably impairing the reaction efficiency.

专利号:US-5066784-A 优先权日:1987-04-24 标 题 :Method for using substrate in peptide syntheses 发明人:SHERRINGTON DAVID C; SMALL PHILIP W 权利人:UNILEVER PATENT HOLDINGS 摘要:A substrate comprises a porous polymeric material having a porosity of at least 75% and comprising pores having a diameter within the range 1 to 100 μm and being interconnected by a plurality of holes, and a gel or material adapted in use to form a gel which gel or pre-gel materials is contained and retained within the pores of the polymeric material and is adapted in use to interact with a reactive species and can be made by depositing and retaining the gel or a material adapted in use to form the gel within the pores of the porous polymeric material. The high porosity of the porous polymeric material in combination with the retention of the gel within the pores permit high loading capacities, particularly in the area of peptide synthesis to be achieved. The substrate can be employed in chemical synthesis, chromatography techniques, ion exchange and separation techniques.
