Among the different extraction techniques used at analytical and preparative scale,
supercritical fluid extraction (SFE) is one of the most used. This review covers the most …

Supercritical fluids possess the unique properties of behaving like liquids and gases, above
their critical point. Supercritical fluid technology has recently emerged as a green and novel …

Despite the large number of elaborate enantioselective syntheses for the preparation of a
single enantiomer to achieve industrial and scientific goals, the separation and purification …

Dense gas techniques, which utilize the properties of fluids in the vicinity of the critical point,
are increasingly being used for the processing of pharmaceuticals. Dense gases are unique …

An enantioselective intramolecular C (sp 3)–H amination of N-benzoyloxyurea by using a
chiral-at-metal ruthenium catalyst is reported, providing chiral 2-imidazolidinones in yields of …

In answer to the need for a more economic technology for the separation of racemates, a
novel system for reactive enantioselective liquid− liquid extraction (ELLE) is introduced …

Supercritical fluids have been applied for many years for the separation of solutes from
