Density functional theory calculations shed light on the conformational prerequisites for the [2+2] photocycloaddition. The bicyclic key structures could be readily transformed into γ‐cyclobutane amino acids.

An efficient route to 3-benzylpyrrolidines using a zirconium-mediated cyclisation both in solution and on a solid support is reported. 3-Benzylidine-pyrrolidines, 3-aryl-pyrrolidines and 4-arylpiperidines were also synthesised.

We have developed a rapid two-step synthesis of substituted 3-azabicyclo[3.2.0]heptanes which are attractive building blocks for drug discovery. This new method utilizes very common chemicals, benzaldehyde, allylamine, and cinnamic acid, via intramolectular [2+2]-photochemical cyclization.
