Title: A process for the manufacture of adenosine-5-diaralkyl-phosphate derivatives and adenosine-5-phosphate and 5-pyrophosphate derived therefrom
IPC: C07H19/20
Filed: 1947-02-05
Abstract: Adenosine - 51 - diaralkyl - orthophosphates in which the hydroxyl groups in the 21- and 31-positions of the b -furanoso side chain are protected, e.g. by two acyl groups or by a dialkyl methylidene group, are prepared by treating adenosine, in which the said hydroxyl groups are protected, with a diaralkyl halogenophosphonate in the presence of a tertiary base. Hydrolysis of the product gives adenosine-51-aralkyl-orthophosphate which is hydrogenolysed to adenosine - 5 - orthophosphate.  The hydrolysis and hydrogenolysis steps may take place in the reverse order.  By treating the metal salt of adenosine-51-aralkyl-orthophosphate, such as the silver salt, with a diaralkyl halogenophosphonate and subsequently removing the diaralkyl groups by hydrogenolysis, adenosine-51-pyrophosphate is obtained.  The preferred starting material is 21 : 31-iso-propylidene-adenosine, but 21 : 31-diacetyl-adenosine may also be used.  In examples: (1) 21 : 31-isopropylideneadenosine in pyridine is treated with dibenzyl chlorophosphonate to give 21 : 31-isopropylideneadenosine-51-dibenzyl-orthophosphate which is hydrogenated with a palladium oxide catalyst and hydrolysed to give adenosine-51-orthophosphate and (2) 21 : 31-isopropylidene adenosine-51-dibenzyl-orthophosphate prepared as in (1) is hydrolysed to adenosine-51-benzylorthophosphate which is converted to the silver salt and treated with dibenzylchlorophosphonate to give a tribenzyl pyrophosphate which is in turn hydrogenolysed to adenosine-51-pyrophosphate. Adenosine-51-pyrophosphate forms an acridine salt.

Filed: 1927-02-07
Abstract: 265,629. Akt.-Ges. Brown, Boveri, et Cie. Feb. 5, 1926, [Convention date]. Heating water.-In industrial power plants required to yield large quantities of hot water, the water which flows through a condenser 4 receiving exhaust steam from a prime mover 1 is used as the supply of hot water. A thermostat 5 in the outflow pipe 3 is adapted, when the temperature is too low, to open a valve 6 admitting live steam to the condenser, and when the temperature is too high, to open a valve 7 allowing hot water to run away. If the prime mover 1 is connected in parallel with other prime movers, its operation is arranged to yield an amount of exhaust steam sufficient to heat the required amount of hot water. In this case the valve 7 is omitted and the thermostat operates the supply valve by the prime mover. The valves are operated by loaded pistons 8, 9, controlled by oil under pressure admitted through pipes 10, 11, or by systems of levers. In the case of a prime mover tapped to yield a supply of heating steam, the valve 6 is arranged to supply additional live steam to the pipe conveying heating steam tapped from the prime mover.
