3-[(3-(Trimethoxysilyl)propyl)thio]propane-1-oxy-sulfonic acid: An efficient recyclable heterogeneous catalyst for the synthesis of 3,4-dihydropyrimidin-2(1H)-ones/thiones
An efficient method for the synthesis of 3,4-dihydropyrimidin-2(1H)-ones and thiones through one-pot three-component reaction of ethyl acetoacetate, aryl aldehyde and urea or thiourea in ethanol using 3-[(3-(trimethoxysilyl)propyl)thio]propane-1-oxy-sulfonic acid as catalyst is described. The use of...
