1-Amino-4,4-difluorocyclohexanecarboxylic acid as a promising building block for drug discovery: design, synthesis and characterization

1-Amino-4,4-difluorocyclohexanecarboxylic acid has been designed as a fluorinated analogue of the pharmacologically relevant 1-aminocyclohexanecarboxylic acid. The synthesis has been performed in three steps from a commercially available material in 22% overall yield. An impact of fluorine atoms on conformation, lipophilicity, acidity and fluorescent properties of the amino acid has been studied. Various practical applications of the obtained compound are suggested.
