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

Shake it up baby! Simply shaking a polymer‐supported reagent and the racemic amine at room temperature kinetically resolves a broad range of N‐heterocycles with good selectivity. The polymer‐supported reagents are robust, easy to regenerate, and can be reused dozens of times. Cleavable acyl groups can be used to give access to both amine enantiomers in a single resolution.
