Paragraph 0043-0044; 0045-0046, (2019/01/08)
The invention discloses a thiourea polyether bridged chiral molecular tweezer and a preparation and an application thereof. The thiourea polyether bridged chiral molecular tweezer takes a thiourea polyether chain as a linking group, and the ent-beyerane skeleton is taken as a chiral arm, and a structure is as shown in a formula (I) or a formula (II). The present invention provides the applicationof the thiourea polyether bridged chiral molecular tweezer for identifying a chiral molecular object, wherein the chiral molecular object is D/L-amino acid ester hydrochloride. The synthesized molecular tweezer has certain chiral recognition performance for D/L-amino-acid ester hydrochloride, and can be used for chiral recognition and separation of enantiomers.
