Abstract
In this non-comprehensive review a selection of tandem processes combining sigmatropic rearrangement with Diels–Alder reactions is presented. The synthetic utility of these two transformations is indisputable as they can lead to complex natural products in an efficient and selective way. Most of the examples presented here have been chosen in view of their application to natural products synthesis. The emphasis of the discussion is put on the illustration of new strategic disconnections becoming accessible thanks to tandem processes.
Keywords: Diels–Alder, cycloaddition, sigmatropic rearrangements, tandem cascade, tactical combination, retrosynthesis.

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
