Furo(3,4-d)pyrimidine-2,4-dione derivatives and intermediates thereof

摘要

The synthesis of furo[3,4-d]pyrimidine-2,4-dione derivatives and their urea intermediates is described. The novel urea intermediates and furo[3,4-d]pyrimidine-2,4-dione derivatives are general vasodilating agents and anti-hypertensive agents. The compounds are useful as cardiovascular agents.
