L-prolinamide/PPTS system was developed to catalyze Robinson annulation of 1,3-cyclohexanedione derivatives. Using this system, the functionalized carbon chain of Wieland-Wiescher ketone could be synthesized in high enantioselectivity, which was a useful synthon for structural diversity of total synthesis of natural product.
