Convergent and divergent strategies for the synthesis of viologen dendrimers with 1,3,5-tri-methylene-branching units are discussed. The title compound is easily transformed into 1-[3,5-bis(hydroxymethyl)benzyl]-4-(pyridin-4-yl)pyridinium hexafluorophosphate, which is used in sequential growth and activation steps as a CB2 compound in the cascade-type dendrimer synthesis (B = -OH, activation = -OH → Br). Analysis of the dendrimer structure reveals that three torsional angles, that is, τ1 between the two pyridinium units, τ2 between the methylene and pyridinium and τ3 between the methylene and phenyl, determine the conformational space of the dendrimers. We report here the crystal structure of 1-[3,5-bis(hydroxymethyl)benzyl]-4-(pyridin-4-yl)pyridinium as PF6- salt which represents the smallest subunit of the dendrimer that shows the same three torsional angles. The crystal structure together with the results from PM3 calculations opens an avenue to judge the structure of benzylic viologen-based dendrimers.

Fukunaga, Kyoko,Tsukida, Takahiro,Moriyama, Hideki,Kondo, Hirosato
, p. 2365 - 2367 (2007/10/03)
We have designed a series of simple rigid compounds (2) having a phenyl ring attached to three essential groups necessary for selectin binding, i.e., a fucose unit, a carboxylic acid, and the hydrophobic part. In this series of compound 2, 2a exhibited strong inhibitory activity in in vitro P-selectin mediated cell adhesion assay. The novel type of compound 2a would be a potential lead compound for selectin antagonist.
Isophthalate ester-terminated dendrimers: Versatile nanoscopic building blocks with readily modifiable surface functionalities
Leon, Jeffrey W.,Kawa, Manabu,Fréchet, Jean M. J.
, p. 8847 - 8859 (2007/10/03)
The preparation and modification of highly functionalized polyether dendrimers containing a versatile diethyl isophthalate terminal group is presented. The convergent synthesis consists of the construction of diester-terminated dendrons containing benzylic bromide functions at the focal point and their subsequent attachment to 4,4'-biphenol cores. Dendrons up to the third generation can be prepared using recrystallization alone as the primary means of purification, allowing the synthesis to be performed on the scale of tens to hundreds of grams. The third and fourth generation bidendron dendrimers (with 32 and 64 terminal ester functionalities, respectively) have been subjected to a variety of surface modification reactions including hydrolysis, ester interchange, and amide-ester interchange, many of which proceed with complete conversion of the functional groups and in high isolated yield. The addition of alcohols such as benzyl alcohol or a first generation 3,5-di(benzyloxy)benzyl alcohol dendron to the dendrimer surface serves to increase the generation number of the dendrimers by one or two in what amounts to a 'double convergent growth' approach. The analysis of these structurally precise dendrimers by matrix-assisted laser desorption ionization time of flight is described.
