The discovery of a novel 2-aminotetrahydropyridine class of BACE1 inhibitors is described. Their pKa and lipophilicity were modulated by a pending sulfonyl group, while good permeability and brain penetration were achieved via intramolecular hydrogen bonding. BACE1 selectivity over BACE2 was achieved in the S3 pocket by a novel bicyclic ring system. An optimization addressing reactive metabolite formation, cardiovascular safety, and CNS toxicity is described, leading to the clinical candidate JNJ-67569762 (12), which gave robust dose-dependent BACE1-mediated amyloid β lowering without showing BACE2-dependent hair depigmentation in preclinical models. We show that 12 has a favorable projected human dose and PK and hence presented us with an opportunity to test a highly selective BACE1 inhibitor in humans. However, 12 was found to have a QT effect upon repeat dosing in dogs and its development was halted in favor of other selective leads, which will be reported in the future.

Early chemical development studies into the best way of assembling AZD9742, an antibacterial drug candidate, have involved swapping the order of two reductive aminations. The orthogonally functionalized aminopiperidine partner for these couplings is now enantioselectively synthesized using ruthenium-catalyzed asymmetric hydrogenation. The challenge of controlling defluorination through an appropriate catalyst choice has hitherto prevented this revised sequence from reaching its full potential. However, it is still shown to allow access to the active pharmaceutical ingredient in a stereochemically pure form and has been demonstrated on a multikilogram scale. The reductive aminations in both the original and revised sequences provided different scale-up challenges, and the solutions implemented are described.

This Letter describes the synthetic routes to challenging pyridyl analogues of 2,3-dihydro-1,4-benzodioxin- 6-carbaldehyde which were key intermediates for our antibacterial medicinal chemistry programme. All routes described started from kojic acid (8) and have been used to give multigram quantities of each aldehyde.
