The present disclosure features a condensation reaction and a luciferin-unmasking reaction that can be carried out under physiological conditions. In general, the condensation reaction involves reacting a bicyclic reactant with an aminothiol derivative, generating a luciferin or luciferin derivative. A luciferin can provide detectable luminescence. A luciferin derivative can be unmasked to provide detectable luminescence in a luciferin-unmasking reaction. The present disclosure provides bicyclic reactants and aminothiol derivatives suitable for use in the condensation reaction. The condensation and luciferin-unmasking reactions find use in a variety of applications, which are also provided.
