Multigram synthesis of 2- and 3-monofluorinated cyclobutane building blocks was disclosed. In both cases, fluorocyclobutanecarboxylic acids were the key intermediates used to obtain all other derivatives, e. g., amines, alcohols, bromides, thiols, sulfonyl chlorides, etc. For both target chemotypes, diastereopure cis- and trans-isomers of the corresponding carboxylic acids and amines were obtained
