[Uses]

Reactant for:
  • Enantioselective synthesis of polycyclic coumarins via in situ formed primary amine-imine-catalyzed asymmetric Michael addition to cyclic enones
  • Preparation of dicoumarol analogs as inhibitors of human NAD(P)H quinone oxidoreductase-1 (NQO1) as agents active against human pancreatic and colon cancer cells
  • Imidazolidinecarboxylic acid-catalyzed asymmetric Michael reaction with unsaturated ketones in a highly atom-economic catalytic one-step formation of optically active warfarin anticoagulant
  • Asymmetric synthesis of functionalized α-keto esters and their hemiketal and hemiaminal derivatives via direct Michael addition with unsaturated α-keto esters catalyzed by bisoxazoline-copper(II) complexes
