title: Flexible synthesis, structural determination, and synthetic application of a new C1-symmetric chiral ammonium betaine.
abstract: A C(1)-symmetric chiral ammonium betaine has been developed, and its intramolecular ion-pairing structure in solid state and its catalytic performance to achieve the highly stereoselective Mannich-type reaction of 2-alkoxythiazol-5(4H)-ones are revealed.
