Abstract
The replacement of 4-hydroxyl group of aminopyrimidinols by sulfhydryl in one step, through the action of phosphorus pentasulfide in triethylamine or 3-picoline. 5-Acylamino-6-amino-4-pyrimidinols were treated with phosphorus pentasulfide in pyridine, to yield thiazolo [5, 4-d] pyrimidine and 6-purinethiol compounds. The yield of both two type compounds were changed according to a functional group in the starting substance. These products, in addition, other 6-purinethiol and related compounds were screened as to their antiviral activities on poliomyelitis virus. Any of the compounds, however, did not exert a significant activity on the virus.
