The first and key step was the formation of the corresponding N-benzyltetrahydroquinolines 5 via a "one pot" three-component cationic imino Diels-Alder cycloaddition from readily available N-benzylanilines, inexpensive formalin (37% formaldehyde in methanol), and a commercially available trans-anethole (and isoeugenol) in the presence of B[F.
60], were synthesized using Knoevenagel reactions between (E)-4-((4-(4-(dimethyl amine)styryl)phenyl) (phenyl)amino) benzaldehyde 9 and cyanoacetic acid, also using a 1,3-dipolar cycloaddition reaction with N-octylglycine and fullerene [C.
Recently, the Huisgen 1,3 dipolar cycloaddition of azides to alkynes to yield 1,2,3 triazoles has emerged as a highly useful and premier example of click chemistry [10-15].

They are viewed as building blocks with the proviso that they could be synthesized from thiophenes directly and would prove suitable cyclic dienes for cycloaddition reactions that would lead to multi-functionalized arenas (Thiemann et al.

The copper-catalyzed variant of Huisgen azide-alkyne cycloaddition (CuAAC) fits the concept well and is one of the most popular prototype click reactions to date.
The complex was found to have the same basic structure as the primary ozonide defining the reaction coordinate of the 1,3-dipolar cycloaddition leading to the primary ozonide shown in Fig.

His design employs either polyesters (more sustainable due to access to bio-based raw materials) or poly-imides (for high-temperature applications) that are functionalized with cyclobutane substrates through the photochemistry of maleic anhydrides, which undergo a [2[Plus]2] cycloaddition reaction to form cyclobutanes when exposed to one wavelength of light and the reverse when exposed to another.
