Description

Application

The following hydroxamic acid catalyst was shown by Bode and coworkers to assist in the kinetic resolution of cyclic amines through acylation of one enantiomer, which can be controlled using either the (R or S)- or (S or R)-Bode Kinetic Resolution Catalyst, both of which are also available through Sigma-Aldrich.
It can also be employed in the preparation of nonracemic piperidines by kinetic resolution using an α-hydroxy-α′, β-unsaturated ketone in the presence of a pyrrolotriazolium salt.

Other Notes

Expanded substrate scope and catalyst optimization for the catalytic kinetic resolution of N-heterocycles
