Enantiomeric resolution of fluorous mixture by chiral CD columns: asymmetric reduction of a mixture of fluorous ketones
摘要:
Asymmetric reduction of a mixture of four fluorous ketone analogues was carried out with (R)-oxazaborolidine as a catalyst. The fluorous mixture products were resolved by a reverse phase HPLC with chiral beta-cyclodextrin column to result in good separation of the enantiomers. (C) 2003 Elsevier Ltd. All rights reserved.

The hydroperfluoroalkylation of electron-deficient olefins with perfluoroalkyl iodides promoted by a zinc/viologen system is described. Interestingly, no iodoperfluoroalkylation product was observed without the presence of radical H-donor.
