Organic Mechanisms: Reactions, Stereochemistry and Synthesis
2.9 Preparatively Useful SN2 Reactions: Alkylations The three-part Figure 2.31,
with a list of synthetically important reactions, shows the various nucleophiles that
can be alkylated via SN2 reactions. This list refers to alkylations with alkyl ...

carbenium ions was considered. It is now known with certainty that this
intermediate is a carbonium ion; it is known as a nonclassical carbocation. In the
carbonium ...

When G1, G2 and G3 are separated preparatively at low resolution HPLC, the
fractions then concentrated to approximately the original concentration and finally
heat-sterilized (120 °C, 30 min) each fraction reassumes a ratio of G1, G2 and G3

Studies on the selective silylation of methyl a- and g-D-aldohexopyranosides with
tert - butyldimethylsilyl 21 chloride have revealed some preparatively useful
reactions. Thus methyl 2,6-di-O-tert - butyldimethy lsilyl-a-D-glucopyranoside is ...

Preparative Liquid Chromatography
Gangliosides, which are of interest since they play a role in human lipidoses,
were separated preparatively into mono-, di-, and trisialogangliosides on layers
of silica gel with the mobile phase chloroform-methanol-2 5 N ammonia (60 40:9

For all other compounds in the tables, a preparatively enriched enantiomer was
used for the racemizations. Such samples were characterized by physical
methods, although in the present chapter the corresponding data are given for
some ...

... of 1% Na amalgam” proceeds more slowly, the reaction with 2.5 M HZSO4
being 97—98% complete at RT after 45 min with ZnS and 120 min with CdS; at
acid strengths up to 0.25 M the reactions are too slow to be useful preparatively.
