Chiral salts of dithiophosphoric acids on the basis of organic nitrogen compounds.

The reactions of O,O-diterpenyl dithiophosphoric acids with pyrimidine (cytosine, uracil and thymine) and purine (adenine and guanine) bases, rhodanine, melamine and xymedon were carried out to yield the substituted pyrimidinium and other salts of dithiophosphoric acids. The antimicrobial activity of salts obtained from xymedon and melamine were evaluated. [ABSTRACT FROM AUTHOR]
