  Correspondence between Molecular Functionality and Crystal Structures. Supramolecular Chemistry of a Family of Homologated Aminophenols

  摘要：

  The crystal structures and packing features of a family of 13 aminophenols, or supraminols, are analyzed and correlated. These compounds are divided into three groups: (a) compounds 1-5 with methylene spacers of the general type HO-C6H4-(CH2)(n)-C6H4-NH2 (n = 1 to 5) and both OH and NH2 in a para position; (b) compounds 1 a, 2a, 2b, 2c, and 3a in which one or more of the methylene linkers in 1 to 3 are exchanged with an S-atom; and (c) compounds 2d, 1b, and 6a prepared with considerations of crystal engineering and where the crystal structures may be anticipated on the basis of structures 1-5, 1 a, 2a, 2b, 2c, and 3a. These 13 aminols can be described in terms of three major supramolecular synthons based on hydrogen bonding between OH and NH2 groups: the tetrameric loop or square motif, the infinite N(H)O chain, and the beta-As sheet. These three synthons are not completely independent of each other but interrelate, with the structures tending toward the more stable beta-As sheet in some cases. Compounds 1-5 show an alternation in melting points, and compounds with n = even exhibit systematically higher melting points compared to those with n = odd. The alternating melting points are reflected in, and explained by, the alternation in the crystal structures. The n = odd structures tend toward the beta-As sheet as n increases and can be considered as a variable series whereas for n = even, the beta-As sheet is invariably formed constituting a fixed series. Substitution of a methylene group by an isosteric S-atom may causes a change in the crystal structure. These observations are rationalized in terms of geometrical and chemical effects of the functional groups. This study shows that even for compounds with complex crystal structures the packing may be reasonably anticipated provided a sufficient number of examples are available.

  PdCl 2 / DMSO催化的巯基-二硫键交换：不对称二硫键的合成

  摘要：

  通过使用简单的PdCl 2 / DMSO催化系统与对称的二硫化物进行硫醇交换，可以有效地制备不对称的二硫化物。给定的方法具有出色的官能团耐受性，广泛的底物范围和操作简便性。该反应对于诸如肽和药物之类的生物活性支架的后期功能化特别有用。还已经制备了含二硫化物的有机染料。这种转化可以扩展到硫醇-二硒化物或硫醇-二碲化物交换，从而提供RS-SeR'或RS-TeR'。
