presented for synthesis of the first examples of chiral, bridged resorcinarenes with functionality in the bridge as possible sites for intracavity asymmetric catalysis. A preliminary study comparing unfunctionalised with functionalised lines using the enantio selective addition of diethylzinc to benzaldehyde as a probe reaction, provides compelling evidence for intracavity catalysis.

提出了用于合成第一个手性、桥连间苯二酚的方法,在桥中具有功能性,作为腔内不对称催化的可能位点。使用二乙基锌与苯甲醛的对映选择性加成作为探针反应比较未功能化和功能化线的初步研究为腔内催化提供了令人信服的证据。((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)。
