The topic Polycyclic Aromatic Hydrocarbons has been reviewed by different authors in the last decades [26]. The most complete summary of classical synthetic routes to PAHs may still be found in Eric Clar s Polycyclic Hydrocarbons [26a]. Most recently, Ronald G. Harvey reviewed the syntheses and characteristics of PAHs up to seven rings in a very comprehensive fashion [26 f] in his book Polycyclic Aromatic Compounds . Recent advances in the synthesis of PAHs are published in all major journals of organic chemistry, in Polycyclic Aromatic Hydrocarbons [27], and presented during the regular ISNA [28] and ISPAC [29] conferences. 

The last part of this section concentrates on the synthesis of fuUerene fragments possessing fulvalene it-systems. Recent advances in fuUerene chemistry have attracted much interest in bowl-Uke polycyclic aromatic hydrocarbons (PAHs)... 

If nitroalkenes are employed as heterodienes in hetero Diels-Alder reactions instead of nitrosoalkenes, cyclic nitrones are formed. These cycloadducts undergo numerous subsequent reactions, and especially the combination of this hetero Diels-Alder reaction with a 1,3-dipolar cycloaddition is an extremely powerful tool for the synthesis of polycyclic alkaloids. This domino [4+ 2]/[3+ 2] cycloaddition chemistry has been comprehensively reviewed by Denmark and Thorarensen very recently, and this review also covers many hetero Diels-Alder reactions of nitroalkenes being not part of this sequential transformation [5]. Therefore the present article will focus on some selected examples which might highlight the advanced state of the art concerning stereocontrol of these reactions. On the other hand, an insight shall be given into the multitude of polycyclic structures accessible by means of nitroalkene cycloaddition chemistry.
