Abstract
Spirostanes, family of steroidal sapogenins continue to attract attention of organic chemists due to their easily occurring cleavage reactions in F ring and because of the renaissance of many natural structures containing steroid spiroketal moiety characterized by interesting biological activity. This article reviews progress in the steroid spirostanes chemistry that was published between 1992 and 2010.
Keywords: Steroids, saponins, steroidal sapogenins, spirostanes, natural products, rearrangement reaction

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
