New Synthesis of 2‐Polyfluoroalkyl Substituted 1,4,5,6‐Tetrahydro‐pyrimidines and 4,5,6,7‐Tetrahydro‐1H‐1,3‐diazepines

Abstract

A new efficient method for the preparation of 2‐polyfluoroalkyl substituted 1,4,5,6‐tetrahydropyrimidines and 4,5,6,7‐tetrahydro‐1H‐1,3‐diazepines by the reaction of polyfluoroalkanethiocarboxylic acids amides and 1,3‐propylenediamine or 1,4‐buthylenediamine is presented.

Keywords:

• aliphatic diamines
• 1,3‐azoles
• thioamides
• organic synthesis
