Abstract
Recent developments in the microwave-assisted synthesis of carbo- and heterocyclicsystems are reviewed with the focus on diversity-oriented cycloaddition reactions. Ineed, these reactions represent one of the most important endeavors in chemistry and are of considerable interest in the synthesis of carbo-and heterocyclic compounds from simple unsaturated systems, and allow the creation of more than two bonds in one step. This review summarizes recent literature (2006-2013) on advances regarding [3+2], [4+2] and [2+2] cycloadditions including their miscellaneous version. Advantages of microwave dielectric heating are highlighted by comparison with conventional thermal conditions. In particular, we describe here the microwave effect, reaction media including solvent-free transformations and more ecological processes in the context of green and environmentally benign chemistry.
Keywords: [2+2] cycloaddition, 1, 3-dipolar cycloaddition, carbocycles, diels-alder, green catalysis, green chemistry, heterocycles, microwave synthesis.

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
Electrochemical C-X bond formation
Conventional methods for carrying out carbon–X bond formation are typically conducted at harsh reaction conditions, and rely on expensive catalysts as well as the use of stoichiometric, and perhaps toxic, oxidants. In this regard, electrochemical synthesis has recently been recognized as a sustainable and scalable strategy for the construction of ...read more
