Pirkle-Concept
p-Acceptors Chiral
Columns
The first Pirkle-concept
chiral stationary phases (CSP’s) were p-electron
acceptors. They resolve enantiomers that are p-electron
donors, the p-electrons being supplied by aromatic
groups within the enantiomers. The phenylglycine and leucine
CSP’s are based on the 3,5-dinitrobenzoyl derivatives of
phenylglycine and leucine, respectively.
The Pirkle-concept columns can be used to separate a wide range of optical isomers, including those of alcohols, sulfoxides, bi-b-naphthols, and b-hydroxysulfides.
a-Burke 2 Chiral
Columns
The a-Burke
2 is a p-electron accepting chiral stationary phase
specifically designed for the enantioseparation of underivatized b-blockers.
Pirkle-Concept
p-Donor Chiral Columns
The second series of
chiral stationary phases are p-electron donors. They are designed to
separate amines, amino acids, alcohols, and thiols that have been
derivatized with a p-electron acceptor. These p-donor
columns are the Pirkle-concept naphthylleucine.
