1,8-Diazabicyclo[5.4.0]undec-7-ene (commonly known as DBU) is a strong, non-nucleophilic organic base widely used in organic synthesis. It acts as a catalyst and proton acceptor in reactions such as eliminations, condensations, and cyclizations. Due to its high basicity and low nucleophilicity, DBU is valuable in pharmaceutical and fine chemical manufacturing processes.
