Synthesis and characterization of functionalized dihydropyrimidinones via one-pot isocyanide-based three-component reaction of N-formyl urea and dialkyl ACETYLENEDICARBOXYLATES

Abstract

The reactive intermediate generated by the addition of alkyl isocyanides to dialkyl acetylenedicarboxylates was trapped by N-formyl urea to produce highly functionalized dihydropyrimidinones in fairly good yields.
