Highly enantioselective as well as diastereoselective catalytic vinylogousMannichreactions have been accomplished for the first time with aliphatic straight-chain aldimines and O,O-silylketene acetals and furnish valuable synthetic building blocks in high enantiomeric purity. vinylogousMannichreaction - phosphoric acid - organocatalyis - contact ion pair - dienolate - BINOL
