Abstract
The application of 9,10-dihydroanthracene in a sequence of dehydrogenation/Diels-Alder cycloaddition reactions with a variety of N-substituted maleimides is described. The in situ transformation of the 9,10-dihydroanthracene into the corresponding anthracene, which is acting as a diene, is accelerated by activated carbon (Darco® KB). The anthracene/maleimide cycloadducts thus obtained might offer some important biochemical applications. The role of the activated carbon in this domino reaction is to accelerate the elimination of hydrogen from the 9,10-dihydroanthracene. The starting maleimides (i.e., dienophiles) were shown to also act as the actual oxidants as they are transformed into the corresponding succinimides. However, the atmospheric oxygen, at least partially, also plays the role of oxidant.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
Chemistry and Biology of Carbohydrates
Carbohydrates are one of the most abundant natural products and are considered to be extremely important biomolecules for their ever-increasing impact on chemistry and biology. Their role in several important biological processes, notably energy storage, transport, modulation of protein function, intercellular adhesion, malignant transformation, signal transduction, viral, and bacterial cell ...read more
Electrochemical C-X bond formation
Conventional methods for carrying out carbon–X bond formation are typically conducted at harsh reaction conditions, and rely on expensive catalysts as well as the use of stoichiometric, and perhaps toxic, oxidants. In this regard, electrochemical synthesis has recently been recognized as a sustainable and scalable strategy for the construction of ...read more
