Synthesis of Novel and Complex Tetrahydroquinazolinedione and Dihydro­pyrido[2,3-d]pyrimidine Derivatives via a One-Pot [4+2]-Cycloadddition Strategy

Abstract

A mild and efficient protocol for the synthesis of various tetrahydroquinazolinedione and dihydropyrido[2,3-d]pyrimidine-2,4-dione templates from uracil derivatives utilizing a [4+2]-cycloaddition strategy in a one-pot reaction has been developed.
