Perfluoroalkane-tagged chiral auxiliary – application to stereoselective synthesis of a beta-amino acid building block

The advantage of tagging organic compounds or biomolecules with perfluoroalkane groups has led to the publication of several research articles by many. Extending this to the chiral auxillaries is no exception. Several such fluorous oxazolidinone based chiral auxillaries have been … Continue reading

Fluorescence tagging using fluorous-trap fluorogenic reagents

Fluorescent labelling of bioactive materials or other chemicals is a pretty straight forward technique. However, the removal of excess fluorescent reagent from the product is often found to be challenging especially when dealing with highly sensitive detection of analytes. When the … Continue reading

Thermomorphic perfluoroalkylated-pyridines catalyzing aldol condensation

Aldol condensation is one of the most fundamental and important carbon-carbon bond-forming reactions wherein an enolate ion reacts with a carbonyl compound to form a beta-hydroxyaldehyde or beta-hydroxyketone which upon dehydration results in a conjugated enone. The reactions are usually … Continue reading

Fluorous surfactants as new spermicidal contraceptives?

Of late, fluorous surfactants (detergents) have been increasingly making their way into various biomedical and pharmaceutical applications. Another new addition to this family is a recent patent (WO2009/026375) filed by Lehigh University that describes the spermicidal and microbicidal properties of fluorous … Continue reading

Are fluorinated surfactants less cytotoxic?

As per a recent communication (New J. Chem., 2008, 32, 2169), this indeed appears to be the case, at least for single-tailed glucopyranoside surfactants compared to their hydrocarbon counterparts.  Non-ionic surfactants of this type are of interest in biomedical applications, … Continue reading
