Asymmetric Ion-Pairing Catalysis of the Reversible Cyclization of 2\u2032-Hydroxychalcone to Flavanone: Asymmetric Catalysis of an Equilibrating Reaction<\/p>\n

Lukas Hintermann and Claudia Dittmer\u00a0<\/p>\n

\u00a0<\/p>\n

The cyclization of nonactivated 2\u2032-hydroxychalcones to flavanones has been realized for the first time with asymmetric induction. In spite of the reversibility of the reactions, this ion-pairing catalysis reaches intrinsic enantioselectivities of up to S = 14.4 (er = 93.5:6.5) and illustrates the characteristic behavior of reversible asymmetric catalyses close to their equilibria.<\/p>\n
