Abstract
The hetero-Diels-Alder reaction is one of the most powerful transformations in the chemistry toolbox for the synthesis of heterocycles. In this article, the recent developments of this reaction are presented involving heterodienophiles such as imines, azenes, carbonyls, thiocarbonyls, and nitroso compounds as well as heterobutadienes such as azabutadienes, diaazabutadienes, oxabutadienes, thiabutadienes, nitrosoalkenes, and nitroalkenes.
Keywords: Aza-Diels-Alder, cycloaddition, heterocycles, hetero Diels-Alder, oxa-Diels-Alder, piperidines, pyrans, thia-Diels-Alder.

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
