work, six isosteviolamino acid conjugates were designed and synthesized through simple condensation on a large scale without protecting group (Scheme). These amphiphilicorganocatalysts mediated asymmetric three‐component Mannichreactions of cyclohexanone and anilines with aromatic aldehydes in the presence of H2O. Meanwhile, the isosteviolprolineconjugate 3b has been established as a highly efficient
