Abstract

The inverse-electron-demand Diels-Alder reaction of electron excessive systems such as enamines, electron-enriched amino heterocycles, and anilines with 2,4,6-tris(polyfluoroalkyl)-1,3,5-triazines was investigated. This study results in the synthesis of a set of polyfluoroalkyl containing pyrimidines, heteroannulated pyrimidines, and quinazolines. Following the elaborated synthetic pathway, l-(β-d-ribofuranosyl)-4,6-bis(polyfluoroalkyl)-1H-pyrazolo[3,4-d]pyrimidines were prepared starting from iso-AIRs.
