We describe a series of improvements to the synthesis of a 3,8-diazabicyclo[3.2.1]octane derivative that result in a reduced step count and higher overall efficiency compared to previously published syntheses. Our method includes optimization and mechanistic understanding of a key diastereoselective cyclization to achieve a >95:5 diastereomeric ratio, as well as demonstration of a unique enzyme-catalyzed amidation reaction using hexamethyldisilazane as both an ammonia source and scavenger. Finally, we identify a novel cocrystal solid form of the target compound that provides improved purity and material properties. Demonstration of the new chemistry to prepare >100 kg of the target compound serves to illustrate the robustness of the new process.

The efficient synthetic routes of three bridged bicyclic amino alcohols were reported. It is conceivable that these compounds could be readily used as compact modules in medicinal chemistry to fine-tune physicochemical and pharmacokinetic properties, in order to eventually improve the overall quality of small molecule drug candidates.
