variety of isoindolinones and tetrahydroisoquinolines via a Lewis acid catalyzed domino Mukaiyama–Mannich lactamization/alkylation is achieved. This transformation comprises a sequential formation of three new bonds through a one-pot, three-component procedure to afford product in moderate to high yields. A concise synthesis of (±)-homolaudanosine (2b) has been achieved using this method.

3-substituted 2,3-dihydroisoindolin-1-ones was achieved with good yields (up to 88%). The process features broad substrate scope, high efficiency, and simplicity, using an one-pot, three-componentMannich/lactamization cascade reaction in the absence or presence of p-toluenesulfonic acid.
