Abstract
A novel boronated aminocyclobutanecarboxylic acid (1) was synthesized for potential use in boron neutron capture therapy. Starting from the readily available 3-(bromomethyl)cyclobutanone ketal (4), several synthetic routes to 1 were evaluated. After several unsuccessful attempts with traditional synthetic methods, a novel synthetic strategy to generate the new boronated cyclic amino acid was developed. The tolerance of the hydantoin group to the selenoxide elimination reaction conditions in the preparation of alkenyl compound 7 proved to be the key step in the new strategy.
