一般描述
N-Benzylcinchonidinium bromide is a chiral phase-transfer catalyst (PTC).
应用
N-Benzylcinchonidinium bromide (BCDBr) can be used:
- To prepare various 4-(bromomethyl)benzenesulfonamides, which are employed as catalysts for asymmetric benzylation reactions.
- As a phase transfer catalyst in the synthesis of organogelators via Michael addition reaction.
- To catalyze the enantioselective alkylation of tert-butyl glycinate-benzophenone Schiff base furnishing the corresponding chiral α-amino acid.
- To resolve symmetric biaryldiols via formation of inclusion complex with diols.
