Photochemical Synthesis of 3-Azabicyclo[3.2.0]heptanes: Advanced Building Blocks for Drug Discovery

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.
