## Abstract PbS microspheres have been synthesized in large scale by a hydrothermal route, in which tungstosilicate acid (TSA) is used. The obtained PbS microspheres have been characterized using Xβray diffraction (XRD), transmission electron microscopy (TEM), Scanning electron microscopy (SEM) and

## Abstract A facile route to synthesize wellβdefined polybutadiene (PBd) DendriMacs is described. In a highly modified approach to that recently published for the synthesis of polystyrene DendriMacs, a G1 polybutadiene (PBd) DendriMac has been synthesized in three simple and high yielding steps. T

Side chains of docetaxel and its isomer were obtained through Staudinger cycloaddition and catalytic hydrogenation of chlorophenyl intermediates, using chlorobenzaldehyde as starting material. Syntheses of three novel chiral azetidinone derivatives through the Staudinger cycloaddition reaction of ch
