-
different sides of the
plane (anti). The
names are
derived from the
diastereomeric four-carbon
aldoses erythrose and threose.
These prefixes are not recommended...
-
resolution involves conversion of the
racemic mixture to a pair of
diastereomeric derivatives by
reacting them with
chiral derivatizing agents, also known...
- diastereomers,
there are
analogous definitions and uses for
diastereomeric excess and
percent diastereomeric excess. As an example, a
sample with 70 % of R isomer...

Diastereomeric recrystallisation is a
method of
chiral resolution of
enantiomers from a
racemic mixture. It
differs from
asymmetric synthesis,
which aims...
- (/ˈθuːdʒoʊn/ ) is a
ketone and a
monoterpene that
occurs predominantly in two
diastereomeric (epimeric) forms: (−)-α-thujone and (+)-β-thujone.
Though it is best...
- d-glucose
molecules exist as
cyclic hemiacetals that are
epimeric (=
diastereomeric) to each other. The
epimeric ratio α:β is 36:64. In the α-D-glucopyranose...
- In the
example shown below, the meso form of
tartaric acid
forms a
diastereomeric pair with both levo- and dextro-tartaric acids,
which form an enantiomeric...
-
Epimerization is a
chemical process where an
epimer is
converted to its
diastereomeric counterpart. It can
happen in
condensed tannins depolymerization reactions...
- so the
product of a Kiliani–Fischer
synthesis is a
mixture of two
diastereomeric sugars,
called epimers. For example, D-arabinose is
converted to a mixture...
- The
isolation of the (1R,2R)-isomer and the (1S,2S)-isomer from the
diastereomeric minor racemate [(1R,2S)-isomer and (1S,2R)-isomer] is
realized by the...
