Carbon-Carbon bond forming processes that involve the deprotonation of a weakly acidic C-H pro-nucleophile using a strong Brønsted base are central to synthetic methodology. Enzymes also catalyze C-Cbondformation from weakly C-H acidic substrates, however, they accomplish this at pH 7 using only collections of non-covalent interactions. Here we show that a simple, bio-inspired synthetic cage catalyzes
