Synthesis of chiral trans-anti-trans-isomers of dicyclohexano-18-crown-6 via an enzymatic reaction and the solid-state structure of one enantiomer

Yamato, Kazuhiro,Bartsch, Richard A.,Broker, Grant A.,Rogers, Robin D.,Dietz, Mark L.

, p. 5805 - 5808 (2007/10/03)

Chiral trans-anti-trans-dicyclohexano-18-crown-6 isomers are synthesized via a lipase-catalyzed reaction. The solid-state structure of the (S)-enantiomer is determined and compared with those reported for 18-crown-6 and trans-syn-trans-dicyclohexano-18-crown-6.

NMR spectra of guest-host complexes of boron and silicon fluorides with crown ethers in nonaqueous solutions

Gel'mbol'dt,Selig,Ganin,Fonar',Ennan

, p. 150 - 151 (2008/10/08)

19F, 11B, and 29Si NMR spectroscopy was used to examine the behavior of the guest-host complexes (BF3·H2O) 2·18-crown-6·2H2O, (BF3·H2O)2·DCH-6B,

Conductance study of binding of some Rb+ and Cs+ ions by macrocyclic polyethers in acetonitrile solution

Shamsipur, Mojtaba,Saeidi, Mahboubeh

, p. 1187 - 1198 (2007/10/03)

A conductance study of the interaction between Rb+ and Cs+ ions and 18-crown-6 (18C6), dicyclohexyl-18-crown-6 (DC18C6), dibenzo-18-crown-6 (DB18C6), dibenzo-24-crown-8 (DB24C8), and dibenzo-30-crown-10 (DB30C10) in acetonitrile solu

Design and synthesis of a new class of nonmacrocyclic alkali metal host compounds

McGarvey, Glenn J.,Stepanian, Marshall W.,Bressette, Andrew R.,Sabat, Michal

, p. 3453 - 3456 (2007/10/03)

A new class of nonmacrocyclic metal ion hosts has been examined that features a polyspirocyclic framework that offers a 1,3,5-triaxial presentation of ligating centers. These compounds are easily synthesized and exploit stereoelectronic influences to preorganize the metal ion binding site. While compounds bearing oxygen substituents (X = OH, OMe) failed to show appreciable binding of alkali metals, the aminated host (X = NHBn) exhibitied strong binding with association constants (Ka) greater than 107-108 as measured by picrate extraction analysis.

SYNTHESIS OF CYCLOHEXANOCROWN ETHERS UNDER CONDITIONS OF PHASE-TRANSFER CATALYSIS

Kusov, S. Z.,Lubenets, E. G.,Kobrin, V. S.

, p. 1234 - 1236 (2007/10/02)

A method was described for production of individual diastereoisomers of cyclohexanocrown ethers from the cis and trans isomers of 1,2-bis(6-chloro-1,4-dioxahexyl)cyclohexane and glycols with phase transfer catalysis.
