Proteolytic cleavage of amyloid precursor protein by β-secretase (BACE-1) and γ-secretase leads to formation of β-amyloid (Aβ) a key component of amyloid plaques, which are considered the hallmark of Alzheimer's disease. Small molecule inhibitors of BACE-1 may reduce levels of Aβ and thus have therapeutic potential for treating Alzheimer's disease. We recently reported the identification of a novel small molecule BACE-1 inhibitor N-[2-(2,5-diphenyl-pyrrol-1-yl)-acetyl]guanidine (3.a.1). We report here the initial hit-to-lead optimization of this hit and the SAR around the aryl groups occupying the S1 and S2′ pockets leading to submicromolar BACE-1 inhibitors.
Synthesis of 1,4-dicarbonyl compounds and 4-keto pimelates by palladium-catalyzed carbonylation of siloxycyclopropanes

Palladium-catalyzed reaction of a siloxycyclopropane with an aryl triflate under carbon monoxide pressure (10-20 atm) in HMPA and that with carbon monoxide in chloroform provides new synthetic routes to 1,4-dicarbonyl compounds and 4-keto pimelates, respectively. The reaction of a siloxycyclopropane with a vinyl triflate, on the other hand, gives an acyloxycyclopropane instead.
