Enantio-differentiation of O-heterocycles using a binol-derived disulfonimide as a chiral solvating agent
Chem Commun (Camb).
.
Abstract
The disulfonimide (R)-1 enables enantio-differentiation of a large scope of chiral O-heterocycles, thanks to the formation of diastereomeric adducts. The underlying H-bond has been investigated by NMR. (R)-1 has been used as a chiral solvating agent (CSA) to determine the stereochemical purity of D/L lactide by (1)H NMR.
