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.
