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.

NOVEL RING TRANSFORMATION REACTIONS AND THEIR APPLICATIONS TO THE SYNTHESES OF POTENTIAL ANTICANCER HETEROCYCLIC COMPOUNDS

Novel heterocyclic ring trasformation reactions developed recently in our laboratory are described.They include pyrimidine to pyrimidine, pyrimidine to pyridine transformations.Also discussed are novel one-step procedures for conversion of 1,3-dimethyluracil derivatives into the pyridopyrimidine system.Some applications of these novel reactions to the syntheses of compounds of biological interest are also described.
