Abstract
Homochirality and related problems have been reviewed. Relative probability of different versions of homochirality arising were estimated on the example of processes, synthesis of organic compounds in space, asymmetric photolysis under circularly polarized light, synthesis of optically active compounds as a result of parity violation, magnetochiral dichroism, chiral amplification, optical active amino acids synthesis and theirs isotope ratios in meteorites, and some other determinate and indeterminate processes. It has been estimated handedness of moving objects as source of chirality. Possible contributions of these processes in homochirality origin in nature have been evaluated. The view is justified that homochirality (and life) origin may be not an accidental event.
Keywords: Asymmetric in vitro and in vivo reactions, enantioselectivity, homochirality.

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
