Studies of Pyrimidine-2,4-diones: Synthesis of Novel Condensed Pyridopyrimidines via Intramolecular Cycloadditions

Prajapati, Dipak,Bhuyan, Pulakjyoti,Sandhu, Jagir Singh

, p. 607 - 610 (2007/10/02)

Suitably functionalised pyrimidine-2,4-diones (1) cyclised intramolecularly to yield the novel furoisoxazolopyridopyrimidines (5) and (9) in excellent yields.Remarkably, the pyrimidone nucleus was unaffected nor were there any side-reactions in this synthesis.
