Treating the benzyl protected 3-hydroxy-1,3-bis(2-hydroxyphenyl)prop-2-en-1-ones solely with PhI(OAc)2 (PIDA) in DCE at room temperature readily furnished the seldom studied spiro-2,2′-benzo[b]furan-3,3′-ones in satisfactory to excellent yields. The hypervalent iodine reagent enables the metal-free cascade spirocyclization resulting in the dual oxidative C?O bond formation. (Figure presented.).

We describe the discovery and optimization of 5-substituted-N-pyridazinylbenzamide derivatives as potent and selective LRRK2 inhibitors. Extensive SAR studies led to the identification of compounds 18 and 23, which demonstrated good in vitro pharmacokinetic profile and excellent selectivity over 140 other kinases. Both compounds demonstrated high unbound fractions in both blood and brain. Compound 18 proved to be brain penetrant, and the high unbound fraction of compound 18 in brain enabled its in vivo efficacy in CNS, wherein a significant inhibition of LRRK2 Ser935 phosphorylation was observed in rat brain following intravenous infusion at 5 mg/kg/h.

Leucine-rich repeat kinase 2 (LRRK2) has been suggested as a potential therapeutic target for Parkinson's disease. Herein we report the discovery of 5-substituent-N-arylbenzamide derivatives as novel LRRK2 inhibitors. Extensive SAR study led to the discovery of compounds 8e, which demonstrated potent LRRK2 inhibition activity, high selectivity across the kinome, good brain exposure, and high oral bioavailability.
