, p. 1865 - 1868 (1994)
Four norbornadiene aromatic derivatives, potentially useful for light energy photochemical storage, were synthesised.Their photophysical properties and the kinetics of the valence photoisomerization reaction into quadricyclanes were investigated.Overall f

Quadricyclane derivatives are shown for the first time to be promising for application as anticancer drugs. The efficiency of such cage compounds is mainly due to thermal action on cancer cells resulting from a C—C bond cleavage in quadricyclane on exposu

The synthesis and properties of various norbornadiene/quadricyclane (NBD/QC) fullerene hybrids are reported. By cyclopropanation of C60 with malonates carrying the NBD scaffold a small library of NBD–fullerene monoadducts and NBD–fullerene hexa

The concept of boronic acid catalysis (BAC) for the activation of unsaturated carboxylic acids is applied to the Diels-Alder cycloaddition between 2-alkynoic acids as dienophiles and various dienes. These [4+2] cycloadditions produce cyclohexadienyl carboxylic acids, which can be oxidized in situ to produce polysubstituted aromatic carboxylic acids. The boronic acid catalyst is suspected to provide activation by a LUMO-lowering effect of the unsaturated carboxylic acid likely via a covalent, monoacylated hemiboronic ester intermediate.
