Sabine Häder,Matthias Ganninger,Siegfried Gableror employing chiral Lewis acids. A point stressed is the synthesis of natural products using hetero Diels-Alder reactions leading to carbohydrates, alkaloids, terpenes, antibiotics, mycotoxins, cytochalasans, antitumor agents and several other classes of natural products..Another topic is the use of

Volker Hüfkensystems bearing a single lactam function. Although the range of reactions described concern only the generation of simple structures without complicated stereogenic properties, most of them seem to bear undiscovered potential with regard to stereoselective synthesis. However, the emphasis of the met

Bettina Stadlerery technologies have emerged that satisfy this technical requirement, including both image-guided noncoplanar and image-guided or electromagnetic-guided gantry based systems. Considering the relatively narrow margins and high purported central biologic potency of SBRT, there are three different pot
