一般說明

N-Benzylcinchonidinium bromide is a chiral phase-transfer catalyst (PTC).

應用

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.

Asymmetric phase transfer catalysis using the Maruoka catalysts has proven to be an ideal method for the enantioselective preparation of natural and unnatural α-alkyl and α,α-dialkyl-α-amino acids from glycine derivati

Asymmetric phase transfer catalysis using the Maruoka catalysts has proven to be an ideal method for the enantioselective preparation of natural and unnatural α-alkyl and α,α-dialkyl-α-amino acids from glycine derivati

Asymmetric phase-transfer catalysis (PTC) has been recognized as a “green” alternative to many homogeneous synthetic organic transformations, and has found widespread application. Synthetically modified cinchona alkaloids are typical chiral organocatalysts used in asymmetric PTC.
