  Generation-Independent Dimerization Behavior of Quadruple Hydrogen-Bond-Containing Oligoether Dendrons

  摘要：

  A new series of self-assembling G1-G3 dendronized dimers bearing oligoether dendrons and a dimeric 2-ureido-4-pyrimidinone (UPy) quadruple hydrogen-bonding core were prepared and characterized. It was found that the nonpolar microenvironment created by the dendrons preserved the UPy unit in its DDAA tautomeric form. As a result, the stabilities of the dimers were exceptionally strong for all three generations (K-dim(.) > 2 x 10(7) M-1 in CDCl3 at 25 degrees C). Furthermore, the steric size of the dendrons did not exhibit a significant effect on their dimerization behavior.

  DOI：10.1002/ejoc.200800134

  日期：2008.5

  A strategy for the introduction of asymmetry into Frechet-type dendrons bearing n-alkyl chains is described. Starting from a methyl 3,5-dihydroxybenzoate core, 3,5-bis(octyloxyphenyl)methoxy and 3,5-bis(alkoxyphenyl)methoxy units are introduced in a stepwise manner. The method is illustrated by the syntheses of four representative compounds having mixed n-octyl/n-butyl, n-octyl/n-hexyl, n-octyl/n-heptyl

  observed in a two-component system containing a viologen-based guest and oxatub[4]arene through the involvement of the three conformers of the host. In addition, an unprecedented threading mechanism involving the tilted conformation of the guests was revealed to be responsible for the very fast kinetics and for the threading of guests with very large stoppers.

  The present invention is directed to a method for reducing the emetogenic effects of PDE inhibitors, and more particularly is directed to compounds having PDE4 inhibition activity with little or no emetogenic side-effects, and chemical methods including benzylation for preparing such compounds. A benzyl group may be attached to either a carbon or nitrogen atom of a PDE4 inhibitor. Suitable benzylation chemistry is to extract a hydrogen from a PDE4 inhibitor, preferably with a base, and then react the resulting nucleophilic PDE4 inhibitor with a benzylating agent, e.g., benzyl bromide or a derivative thereof.

  Amphiphilic homopolymers containing a hydrophilic and a hydrophobic functionality in each monomer unit have been shown to form polar or apolar containers depending on the solvent environment. When presented with a mixture of solvents, these polymeric containers are capable of releasing certain guest molecules. The fundamental mechanism behind these properties is investigated, and the utility of these assemblies in separations has been demonstrated with an example.
