Synthesis of new pyrimidine-containing compounds: 5-(2-(alkylamino)-1,3-dioxo-2,3-dihydro-1H-inden-2-yl)-6-hydroxypyrimidine-2,4(1H,3H)-dione derivatives


In this study, the one-pot reaction between primary amines, 1,1-bis-(methylthio)-2-nitroethene, ninhydrin, and barbituric acid as an enolizable C–H-activated compound provides a simple method for the preparation of 5-(2-(alkylamino)-1,3-dioxo-2,3-dihydro-1H-inden-2-yl)-6-hydroxypyrimidine-2,4(1H,3H)-dione derivatives with potential synthetic and pharmacological interest. This reaction shows attractive characteristics, such as substrate availability, good yields, existence of numerous hydrogen-bonding possibilities in product, and its mild conditions in ethanol media.
