| titleOfInvention | 2,2'-CYCLOCYTIDINE (2,2'-ANHYDROARACYTIDINE) DERIVATIVES AND METHOD FOR THEIR PRODUCTION |
| abstract | Cmpds. (I) are new: (where R is H or H2PP3; Y is H, OH, 1-4C alkyl or 1-4C alkoxy; and X is H, halogen or CH3; at least one of R, X and Y being other than H). This is a Division of 2,244,257. Antivirals and antitumour and anticancer agents. (I) are prepd. by heating corresponding cytidine derivs. of formula (II): with a chlorophosphoric acid and an ester of a carboxylic acid. Pref. chlorophosphoric acids are dichlorophosphoric acid, pyrophosphoryl chloride, esters of these cpds. and/or mixtures of these substances with a material obtd. by addition of water, a 1-8C aliphatic alcohol or of phenol to 0.5-2.0 molar proportions of phosphorus oxychloride or pyrophosphoryl chloride. |
