Intramolecular free-radical addition to propiolate esters has provided a new and a stereoselective route to 14–16 membered -α,β-unsaturated macrocylic lactones from their corresponding ω-iodoalkyl-propionate esters under triphenyltin hydride/AIBN mediated conditions. Attemps to synthesise analogous 10–13 membered lactones proved unsuccessful, resulting in acyclic products derived from direct reduction at the

report on the synthesis of a new family of nonionic dendriticamphiphiles that self-assemble into defined supramolecular aggregates. Our approach is based on a modular architecture consisting of different generations of hydrophilic polyglyceroldendrons [G1-G3] connected to hydrophobic C(11) or C(16) alkyl chains via mono- or biaromatic spacers, respectively. All amphiphiles complex hydrophobic compounds
