Resolution and absolute configuration assignment of a chiral hemicryptophane molecular cage

Chirality. 2010 Nov;22(10):885-8. doi: 10.1002/chir.20876.

Abstract

The racemic hemicryptophane molecular cage 2 was resolved by semipreparative HPLC on Whelk-O1 column. The absolute configuration of each isolated enantiomer was established from the analysis of their circular dichroism spectra and assigned as P-(+)-2 and M-(-)-2.
