Abstract
Consequences of a chiral influence consisting of three independent factors orienting molecules are reviewed and discussed. This influence may affect mutual orientation of reacting molecules leading to absolute asymmetric synthesis. It may also exert different orientation of opposite enantiomers relative to a flat surface which can lead to absolute enantioselective separation. Besides the obvious although not trivial possible applicability in organic synthesis, such a process, when applied to a mixture of monosaccharides may have consequences related to the formation of enantiomerically pure ribose under prebiotic conditions. It is shown that α-DL-ribopyranose is the easiest racemic monosaccharide to get separated to enantiomers.

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
