A direct synthesis of hydroxysemperoside deglucoside
A 1 0-step synthesis of hydroxysemperoside deglucoside has been achieved. The key step is an organopalladium-mediated cyclization that produces a highly functionalized oxabicyclooctane. The remaining functional groups are introduced by addition to the exo face of the fused bicyclic system.

Sonochemically Assisted Synthesis of ZnO Nanoparticles: A Novel Direct Method
Nanocrystalline ZnO particles were prepared by a novel sonochemical route from zinc acetate and sodium hydroxide without any requirement of calcination steps at high temperature and without surfactants. Variations in several parameters and their effects on the structural (crystal size and morphology) properties of nanoparticles were investigated. Characterizations were carried out by X-Ray ...
