Description

Application

Methyl (R)-(+)-3-bromo-2-methylpropionate can be used as a reactant to prepare:
•  (S)-3-(6-Methoxy-pyridin-3-yl)-2-methylpropionic acid methylester by reacting with 5-bromo-2-methoxy pyridine via nucleophilic displacement reaction.
•  Decahydroisoquinoline derivative (NVP-ACQ090) as a potent antagonist of somatostatin sst3 receptor.

It can also be used as a reference compound in the enantioselective alkylation reaction of hydrophobic vitamin B12 derivatives.
