摘要：
本文以二苯基甘脲为建筑模块合成得到一对不对称U型三维结构的拓扑异构体,该不对称分子夹在堆积过程中选择性形成一种异手性自组装二聚体AB1,这种对映选择性自组装主要是分子间CH…O和CH-π两种弱氢键协同作用的结果.其中,CH…O作用在手性识别中起着关键作用.

摘要：
<正>自然界中,天然产物通常具有凹型的空腔或裂缝从而使其更好的包结客体。近年来,被合成出的具有此类空腔的主体化合物,包括分子夹、分子钳、分子碗、分子裂缝及大环化合物等, 在分子识别、分子催化、纳米材料等方面都得到了广泛的应用。设计合成具有空腔的主体化合物仍将是主一客体化学研究的热点之一。

摘要：
A novel and efficient carbon-carbon double-bond formation reaction via coupling of aryl or heteroaryl methyl ketones has been developed. A dimethyl sulfoxide-iodine-CuO system was proven to be efficient for this reaction and afforded the expected products in good yields. A new synthetic strategy, a self-sorting tandem reaction, was involved in this type of reaction and was presented for the first time. © 2006 American Chemical Society.

摘要：
The crystal structure of the nitroxide spin labeled derivative of podophyllotoxin was first reported. X-ray analysis demonstrated that four contiguous chiral centers in the molecule, C1, C2, C3, and C4, adopt cis- (1:2), trans-(2:3), and cis- (3:4) arrangement. ©2006 NRC.

摘要：
We report the X-ray crystal structure of 11 molecular clips and analyze the influence of substituents ( e. g., OMe, Me, and NO2) and their location on the observed crystal packing. Molecular clips 3a and 3b form tapelike structures in the crystal due to pi-pi interactions between the aromatic walls. Compounds 3d, 3eC, and 3fC form dimers driven by critical C-H center dot center dot center dot O interactions and then form tapes driven by pi-pi interactions in the crystal. These two building motifs, pi-pi and C-H center dot center dot center dot O interactions, can be used to rationalize the enantio- and diastereoselectivity observed in the X-ray crystal structures of the remaining five molecular clips. For example, the C-H center dot center dot center dot O interactions are found to dictate the formation of homochiral dimers in the structures of (+/-)-3eT and (+/-)-3fT and to control the diastereoselective formation of 6a(2)-6c(2) dimeric motifs with internal p-dimethoxy-o-xylylene walls. Overall, the results suggest that substituent effects that induce even weak intermolecular interactions ( e. g., C-H center dot center dot center dot O) can be used to reliably control crystal packing within glycoluril-based systems.

摘要：
The molecule of the title compound, C58H42N 4O6, a molecular clip based on the glycoluril framework, occupies a special position on a twofold axis passing through the mid-point of the gycoluril C-C bond. The planes of the central benzene rings in the opposite wings of the molecular clip form a dihedral angle of 41.6 (4)°. No dimers typical for molecular clip packings are observed in the crystal structure of the title compound. © 2005 International Union of Crystallography Printed in Great Britain - all rights reserved.
