Abstract

2-Phenyl-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimtdine-5,7-dione reacts with several nucleophilc reagents via a scheme involving nucleophilic addition with opening of the dioxopyrimidine ring at the C-N bond in the 7–8 positions. The reaction may serve as a method for the synthesis of some asymmetrical pyrazolyl derivatives of malonic acid.
