Conclusion/Summary
• Since discovery the Paterno-Buchi process it hasbecome a tool used in highly oxygenated and stereochemically complex molecules
• It has been cited 94 times according to Web of Science.
• The feasibility and speed of the photo induced reaction makes it a perfect viable process for natural product synthesis.
