- W2734919635 abstract "Cryptophanes are receptors consisting of two bridging concave cyclotribenzylene (CTB) subunits. The formation of cryptophanes in basic aqueous solutions (0.1 m MOD; M = Li, Na, K, and Cs) by disulfide bridge formation has been investigated. Two original CTBs, 1H6 and 2H6, derived from cyclotriphenolene through the introduction of mercaptomethyl and mercapto substituents, respectively, were synthesized. Cryptophane formation by slow oxygenation of 16– was observed only in the presence of Me4N+ as template, which yielded the diastereomeric forms in a ratio of around 82:18. By contrast, the rigid CTB 2H6 yielded a cryptophane stereoselectively without a template. Interestingly, air oxidation of a 1:1 mixture of 16– and 26– in the presence of Me4N+ (0.5–1 equiv./16–) in 0.1 m LiOD led to the exclusive formation of the cryptophane complex [(1·1)6–⊃+NMe4], (2·2)6– being formed only in very minor amounts. No mixed species were detected in the reaction mixtures. The stabilities of the diastereomers of the protonated cryptophanes were calculated in the gas phase by DFT at the ωB97XD 6-311G(d,p) level of theory." @default.
