A facile and simple regioselective synthesis of uracils and their thio analogues has been achieved by cyclocondensation of a common precursor, diazadienium iodide 1, and isothiocyanates 2a,b. The key step in this synthetic process is the preparation of 4-
Straightforward pyrimidine ring construction: A versatile tool for the synthesis of nucleobase and nucleoside analogues

A general route to 1,2,4-trisubstituted pyrimidines is described in one to three steps from a common key precursor, diazadienium iodide 2. An efficient preliminary [4+2] cyclocondensation reaction between the azabutadiene building block 2 and various iso(thio)cyanates constitutes an original construction of the pyrimidine skeleton. Subsequent structural modifications on the heterocycle allow the elaboration of a 1-substituted pyrimidine library that includes nucleoside analogues. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
