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.

Inhibitors of the glucagon-like peptide-1 (GLP-1) degrading enzyme dipeptidyl peptidase IV (DPP-IV) have been shown to be effective treatments for type 2 diabetes in animal models and in human subjects. A novel series of cis-2,5-dicyanopyrrolidine α-amino amides were synthesized and evaluated as inhibitors of dipeptidyl peptidase IV (DPP-IV) for the treatment of type 2 diabetes. 1-({[1-(Hydroxymethyl)cyclopentyl]amino}-acetyl)pyrrolidine-2,5-cis- dicarbonitrile (1c) is an achiral, slow-binding (time-dependent) inhibitor of DPP-IV that is selective for DPP-IV over other DPP isozymes and proline specific serine proteases, and which has oral bioavailability in preclinical species and in vivo efficacy in animal models. The mode of binding of the cis-2,5-dicyanopyrrolidine moiety was determined by X-ray crystallography. The hydrochloride salt of 1c was further profiled for development as a potential new treatment for type 2 diabetes.

Based on the structure characteristics of the lead compounds, 1,1′2-octanedioyl-4,4′-dimethyl-4,4′-dibenzyl dipiperazinium dibromide (2) and 3,8-disubstituted-3,8-diazabicyclo[3.2.1]octanes (DBO), di-(3,8-diazabicyclo[3.2.1]octane) diquaternary ammonium salts 3 a-c were designed and synthesized through a highly practical procedure. Target compounds 3 a-c and the hydrochloride salts of their precursors 10 a-c were evaluated for their in vivo analgesic and sedative activities. Interestingly, the introduction of an endoethylenic bridge in the piperazine of lead compound 2 causes loss of the analgesic activity and increases the toxicity dramatically. This result shows that the flexible conformation of piperazine in compound 2 is favorable for interaction with the receptor, and the quaternization of compounds 10 a-c is the main reason for the toxicity increase.
