cycloreversion was synthesized. Under reductive conditions of the hypoxic cancer cells, a bioorthogonal shunt which releases cytotoxic singlet oxygen via the intermediacy of a fluoride signal becomes operative. The result is a very precise spatio-temporal targeting of singlet oxygen, which opens a new path toward potential therapeutic applications.
