General description

Hydroquinidine, a cinchona alkaloid, is a structural analog of quinidine. It shows antiarrhythmic effect.

Application

Hydroquinidine can be used as a chiral catalyst to prepare:
  • Enantioselective axially chiral phosphamides by N-allylic alkylation reaction between Morita-Baylis-Hillamn (MBH) carbonate and phosphamides.
  • Enantioselective α-amino phosphonates by hydrophosphonylation of N-aryl ketimines.
  • Enantioselective α-hydrazino esters by α-hydrazination of 3-oxoindolines using azodicarboxylate via aza-Michael reaction.
