Abstract
The classical Biginelli reaction has been extended by the use of N-substituted ureas and thioureas. A set of N 1-alkyl-, N 1-aryl-, and N 1,N 3-dialkyl-3,4-dihydropyrimidin-2(1H )-(thi)ones was readily prepared in excellent yield when chlorotrimethylsilane in N ,N -dimethylformamide was used as promoter and water scavenger.
Key words
Biginelli reaction - heterocycles - Lewis acid - multicomponent reaction - parallel synthesis
