Abstract

6-Halonucleosides the sugar residues of which are completely esterified are obtained from the corresponding 6-mercapto compounds by reaction with halogen in solution or suspension in an inert organic solvent, e.g. alcohols, CHCl3, CCl4, aromatic hydrocarbons. Temperatures below 35 DEG C. are suitable, e.g. + 10 DEG to - 10 DEG C. Numerous acetylated or benzoylated 6 - mercapto - purine and - pyrimidine nucleosides are specified as starting materials including compounds containing further mercapto groups in the 2- and/or 8-positions these being also replaced by halogen in the reaction, amino groups, hydroxy groups and bromine atoms. Examples describe the preparation of 6-chloro-, 2 - amino - 6 - chloro -, and 2 - amino - 8-bromo - 6 - chloro - 9 - (21,31,51 - tribenzoyl)-b -D-ribofuranoxylpurines. Reference has been directed by the Comptroller to Specification 924,246.
