3-Substituted 2-pyridones were enantioselectively (68-90% ee) converted into the respective 3-hydroxypyridine-2,6-diones by a sequence consisting of a template-mediated type II photooxygenation and an acid-catalysed rearrangement.
The realisation of Global Cellular Automaton (GCA) using a comparatively high number of communicating finite state machines (FSM) leads to high communication effort. Inside configurable architectures, fixed numbers of FSM and fixed bus widths result in a granularity that makes mapping of larger GCA to these architectures even more difficult. This approach… (More)
We have constructed a pulsed THz imaging system based on the triangulation method. The system is capable of stand-off measurements, especially of retrieving the refractive index in a non-tactile manner even if the thickness of the object is unknown. The distance between emitter and imaged object for the presented measurements was 1.3m. We have measured a… (More)
By the rising complexity and miniaturisation of the device’s dimensions, the density of the conductors increases considerably. Referring to this, locally transient interactions between single physical values become apparent. Therefore, for the investigation and optimisation of integrated circuits it is essential to develop suitable models and simulation… (More)
We present a pulsed terahertz imaging system with a line focus intended to speed up measurements. A balanced 1-D detection scheme working with two industrial line cameras is used. The instrumental characteristics are determined.
The natural product (-)-pinolinone was synthesised via a concise route (six steps, 17% overall yield) from 3-acetoxyquinolone, employing an enantioselective intermolecular [2+2] photocycloaddition as the key step.
The use of a fiber-coupled terahertz TDS system offers new possibilities for angle-resolved reflection spectroscopy. We put the focus especially on angle-resolved scattering from roughened surfaces of both dielectric and metallic surfaces.
