A series of homologous C-nucleoside mimics have been synthesized via an efficient and facile synthetic protocol involving the conjugate addition of purine to sugar derived olefinic ester in good yields. The synthesized compounds were evaluated for their antiplasmodial activity in vitro against both the CQ-sensitive and resistant strains of P. falciparum. Interestingly, all the synthesized nucleoside
There is described a novel method for preparing and isolating novel salts of 6-chloropurine and strong acids. According to the method hypoxanthine is reacted with phosphorus oxychloride in the presence of an organic base to form 6-chloropurine, a solvent is added to the reaction mixture and the latter is reacted with a strong acid to form a 6-chloropurine salt which is then isolated. In a preferred embodiment 6-chloropurine is freed from the salt with water, preferably in the presence of a base. In another preferred embodiment the 6-chloropurine is aminated with various amines.
