Alkynylation of aryl iodides with propargylicamines has been achieved by means of a Sonogashiracoupling using “on water” methods. The use of less than 0.2 mol% of tetrakis(triphenylphosphine)palladium [Pd(PPh3)4] and 1.5 mol% copper(I) iodide [CuI] in the presence of diisopropylethylamine (DIPEA) allows the coupling to proceed at 95 °C yielding moderate to good yields of mono-, bis-, and tris-aminoalkynylbenzene

A series of mono-, di-, and tetravalent galablose (Ga1alpha1-4Gal) compounds were synthesized in good yields by coupling of a general carboxylic acid-bearing sugar building block to dendritic scaffolds based on the 3,5-di-(2-aminoethoxy)benzoic acid branching unit. Furthermore. a poly(amidoamine)- (PAMAM-) based dendritic galabioside was Synthesized containing eight galabiose units. All galabiosides were tested in a hemagglutination assay and a Surface plasmon resonance (SPR) competition assay in order to establish their potency in the binding to the bacterial Gram-positive pathogen Streptococcus suis. A monovalent cralabioside containing a short spacer was used as a reference compound in all the assays. Varations in the scaffold as well as in the spacer arms were introduced to determine their influence on the inhibition. The best inhibitor of hemagglutination was an octavalent galabioside with a minimal inhibitory concentration (MIC) of 0.3 nM, to the best of our knowledge the first, example of inhibition of bacterial binding by a soluble carbohydrate at a subnanomolar concentration.

affinity in multiply bonded supramolecular complexes as they help reduce the entropic penalty of the binding event. This comes at the price that such rigid complexes are sensitive to small geometric mismatches. In marked contrast, nature uses more flexible building blocks. Thus, one might consider putting the rigidity/high‐affinity notion to the test. Multivalent crown/ammonium complexes are ideal for this
