This invention relates to the processes for the preparation of unknown N-1 sulfonyl and N-1,NH-4 disulfonyl derivatives of pyrimidine nucleo bases, general formulae I, II, III, IV, V and VI, and their biological activity.
This type of compounds exhibits strong anticancer activity in vitro on different tumor cell lines whereas cytostatic behavior on normal human fibroblasts is much less pronounced.

The reaction of N1-sulfonyluracil derivatives bearing a 2-hydroxyethyl moiety at the 3-position with NaH under anhydrous conditions at room temperature affords the corresponding 2-oxazolidinone bearing the β-enaminocarbonyl moiety. These products are useful diversifiable precursors toward various β-amino acids and N-heterocyclic compounds.

Conformational chirality and chiral crystallization of N-sulfonylpyrimidine derivatives
1-(1-naphthylsulfonyl)thymine (6) were prepared by the condensation reaction of silylated pyrimidine derivatives with selected sulfonyl chlorides in acetonitrile. Some members of the series showed unexpected crystal properties as a consequence of their conformational chirality in the solid state. Compounds 1 and 5 exhibited chiral crystallization, which was, in the case of 1, accompanied by the formation of racemically
