Synthesis of thietanyl-substituted pyrimidine-2,4(1H,3H)-dions
摘要:
Reactions of 6-methylpyrimidine-2,4(1H,3H)-dione or 5-hydroxy-6-methyl-pyrimidine-2,4(1H,3H)-dione with 2-chloromethylthiirane afforded the corresponding substituted 1-(thietan-3-yl)pyrimidine-2,4(1H,3H)-diones. The calculations in the framework of approximations PBE/3z, B3LYP/6-31G++(d,p) and MP2/6-31G++(d,p) showed that the alkylation occurred at the atom N-1 of the pyrimidine ring.
