A New Way to Build Molecules with Light

Chemists have found a new way to build complex molecules using light. This method is special because it does not need extra steps to prepare the starting materials. Instead, it uses simple acids and light to add parts to molecules called tetrahydroisoquinolines (THIQs). The process involves a catalyst called 9-phenylacridine and visible light. This combination helps to add parts to the THIQs without needing extra steps. The method works well with many different acids and THIQs, making it a useful tool for creating new molecules.This new approach is important because it makes it easier to create molecules that are useful in medicine. It also shows how light can be used to make chemical reactions more efficient and versatile. However, it is important to think about the limitations of this method. While it works well with many acids and THIQs, it may not work with all types of molecules. Also, the use of light and a specific catalyst may not be suitable for all laboratory settings. In the end, this new method is a step forward in synthetic chemistry. It offers a simpler and more efficient way to build complex molecules, which can be useful in many fields, including medicine.
