beta-peptides as catalysts: poly-beta-leucine as a catalyst for the Juliá-Colonna asymmetric epoxidation of enones.
Poly-beta-leucines have been evaluated as catalysts for the Juliá-Colonna asymmetric epoxidation of enones; the beta 3-isomer was found to be an effective catalyst for the epoxidation of chalcone (70% ee) and some analogues.
