Abstract

An efficient and novel approach using highly versatile but less exploited monofluorinated α-oxoketene N,S-acetals as synthons for the synthesis of novel fluorinated multisubstituted pyrimidines and 1,5-benzodiazepines by cyclization with guanidine nitrate and o-phenylenediamine, respectively, has been developed. The synthesized compounds, which carry additional functional groups that allow further functionalization, are of considerable interest as building blocks in medicinal chemistry. X-ray crystallographic studies confirmed the formation of the desired cyclized product.
