N-alkylation of phenobarbital under phase-transfer catalysis conditions
This communication describes a convenient procedure for the preparation of alkylated derivatives of phenobarbital using phase-transfer catalysis without solvent conditions.
Process for preparing pyrimidinetrione derivatives
This invention relates to a process for preparation of pyrimidinetriones. It also relates to novel N-dihydroxyphosphoryl pyrimidinetrione derivatives which may be useful as water-soluble prodrugs of certain pyrimidinetrione compounds.
