A Robust, Recyclable Resin for Decagram Scale Resolution of (±)-Mefloquine and Other Chiral N-Heterocycles
Decagram quantities of enantiopure (+)-mefloquine have been produced via kinetic resolution of racemic mefloquine using a ROMP-gel supported chiral acyl hydroxamic acid resolving agent. The requisite monomer was prepared in a few synthetic steps without chromatography and polymerization was safely performed on a >30 gram scale under ambient conditions. The reagent was readily regenerated and reused multiple times for the resolution of 150 grams of (±)-mefloquine and other chiral N-heterocylces.

Discovery of a novel sulfonamide-pyrazolopiperidine series as potent and Efficacious γ-Secretase Inhibitors
Discovery of a series of pyrazolopiperidine sulfonamide based γ-secretase inhibitors and its SAR evolution is described. Significant increases in APP potency on the pyrazolopiperidine scaffold over the original N-bicyclic sulfonamide scaffold were achieved and this potency increase translated in an improved in vivo efficacy.
