(1S,4S,5S)-4-Bromo-6-oxabicyclo[3.2.1]octan-7-one

It is employed to construct the specific stereochemistry of the cyclohexane diamine core by undergoing ring-opening and subsequent functionalization, such as in the preparation of tert-butyl (1R,2S,5S)-2-amino-5-(dimethylcarbamoyl)cyclohexylcarbamate. (1S,4S,5S)-4-Bromo-6-oxabicyclooctan-7-one is a critical, chiral, bicyclic intermediate employed to synthesize the FXa inhibitor edoxaban.
