  2,7,12-tris<<3,5-bis(methoxymethyl)phenyl>methyl>-10,15-dihydro-3,8,13-trimthoxy-5H-tribenzocyclononene racemate 在 三氯化硼 、 potassium carbonate 作用下， 以 二氯甲烷 、 N,N-二甲基乙酰胺 为溶剂， 反应 12.25h， 生成 1,13,14,21,22,34-hexahydro-30,36,48-trimethoxy-13,21,44-tris<(4-methylphenyl)sulfonyl>-6H,12H,20H,28H-2,5-etheno-9,25-<(methanimino)methano>3,32:17,37-dimethano-7,11:15,19:23,27:29,33-tetrametheno-13,21-benzodiazacyclohexatriacontine racemate

  Host-guest complexation. 60. Rigidly hollow hosts that encapsulate small molecules

  摘要：

  New chiral host systems 1 and 2 possessing C3 symmetry have been designed and synthesized. Molecular models of 1 and 2 indicate they contain small enforced cavities and three portals complementary to small molecules. The crystal structure of 1.2CH3CN shows one molecule of CH3CN is encapsulated and the second exists as a solvate. A crystal structure of 2.2CH3OH shows one CH3OH molecule is encapsulated and a second serves as a solvate. A crystal structure of 2.CH2Cl2 shows the host to be empty and that the CH2Cl2 acts as a solvate to provide (by disorder) a C3 pattern about the C3 axis of the host. In CDCl3 solutions (CDCl3 is too large to occupy its cavity), 1 complexed O2, N2, H2O, and CO2 readily and reversibly (H-1 NMR spectra), particularly at low temperatures. In CDCl3 solution, 1 binds CH3OH with K(a) = 10 M-1, DELTA-G-degrees 295 = -1.4 kcal mol-1, DELTA-H congruent-to -6.6 kcal mol-1, and DELTA-S congruent-to -18 cal mol-1 K-1. It also binds CH3CN, but much more weakly. Triamine 2 in CDCl3 binds O2, N2, and H2O weakly and CH3OH with a K(a) = 47 M-1, DELTA-G-degrees 295 = -2.3 kcal mol-1, DELTA-H congruent-to -8.5 kcal mol-1, and DELTA-S congruent-to -21 cal mol-1 K-1. This host binds CH3CN at 295 K with a K(a) in the range of 1-10 M-1, and CH3CH2OH with a K(a) < 5 M-1. The H-1 NMR signals of the guest's CH2 group of 2.CH3CH2OH indicate the protons to be diastereotopic. The half-life for decomplexation of 2.CH3CH2OH was about 40 min at 25-degrees-C.
