Starting from the thiacalix[4]arene tetraacetate, novel derivatives bearing four ureido or thioureido functions on the lower rim have been prepared. As proven by NMR titrations, these compounds can bind anions via hydrogen bonding interactions and represent the first example of anion receptors in the thiacalixarene series. The thiacalix[4]arene-tetraacetates or diacetates (cone) serve as a starting point for novel thiacalixarenes derivatives bearing urea or thiourea units on the lower rim. As revealed by NMR titration experiments, these compounds are preorganised for anion recognition in organic solvents.

Mmm, a reaction sandwich Using an immunoassay-based technique able to monitor any kind of cross-coupling reaction, a systematic and rapid evaluation of a large panel of random reactions was carried out. This approach led to the discovery of two new copper-promoted reactions: a desulfurization reaction of thioureas leading to isoureas and a cyclization reaction leading to thiazole derivatives from alkynes and N-hydroxy thioureas.
