Published in 2018 at "ELECTROPHORESIS"

DOI: 10.1002/elps.201700273

Abstract: A new single‐urea‐bound chiral stationary phase based on 3,5‐dimethylphenylcarbamoylated β‐cyclodextrin was prepared through the Staudinger reaction of mono (6A‐azido‐6A‐deoxy)‐per(3,5‐dimethylphenylcarbamoylated) β‐cyclodextrin and 3‐aminopropyl silica gel under CO2 atmosphere. The new phase exhibited good enantioseparation performance for… read more here.
