Story summary

Researchers at the National University of Singapore have developed a photocatalytic method that replaces the oxygen atom in oxetane rings with nitrogen, sulfur, or carbon.
The atom-swapping technique simplifies the synthesis of complex cyclic molecules and enables the creation of diverse drug analogs in a single step.
The process uses blue light and a ruthenium photocatalyst to form a dibromide intermediate that can be converted into various saturated heterocycles.
This innovation enhances drug design by streamlining late-stage functionalization and could accelerate drug development across medicinal chemistry and related fields.
