(DHQ)2PYR Chemical Properties,Usage,Production

Uses

(DHQ)2Pyr is a bis-Cinchona alkaloid ligand used in enantioselective synthesis applications. Cinchona alkaloids catalyze many useful processes with high enantioselectivities. Cinchona alkaloids can be used as bases to deprotonate substrates with relatively acidic protons forming a contact ion pair between the resulting anion and protonated amine. This interaction leads to a chiral environment around the anion and permits enantioselective reactions with electrophiles. Amination with diimides at the remote γ-position can be carried out using (DHQ)2Pyr to form a diverse range of highly functionalized amine compounds.
