The present invention provides novel chiral bisamino-ether compounds, and method of preparation and use thereof. The chiral bisamino-ether compounds have the structure of formula (I). The method of preparation includes: using chiral aminomethanol compounds as starting materials to react with halogenated aryl compounds in the presence of a base to give a variety of chiral bisamino-ether compounds. The novel chiral bisamino-ether compounds can be used for asymmetric fluorocyclization of unsaturated heterocyclic compounds with excellent enantioselectivity and great potentials for industrial applications.

Enantioenriched fluorinated heterocycles can be prepared through fluorocyclizations of prochiral indoles (see scheme; Ts=tosyl, Bn=benzyl, Boc=tert‐butoxycarbonyl). More than twenty examples for this cascade fluorination–cyclization, which is catalyzed by cinchona alkaloids and employs N‐fluorobenzenesulfonimide as the electrophilic fluorine source have been explored, and an unprecedented catalytic
Novel amino‐acid‐derived phthalazine reagents have been designed and synthesized for the enantioselectivefluorocyclizations of prochiral indoles. The scope of reaction is evidenced by 28 examples of fluorinated furoindole and pyrroloindole heterocycles bearing various functionalities with up to 99% ee. The resulting enantioenriched fluorinated products are found to be potent AChE inhibitors. Advantages
