A simple and efficient strategy was developed for the synthesis of fused pyrrolo[2,1-a]isoquinoline ring systems. The 5- and 6-substituted isoxazolopyrroloisoquinolines were readily prepared via diastereoselective N-acyliminium ion cyclization of 5-(1-R(or 2-R)-substituted-2-phenylethyl)-6-hydroxytetrahydro-4H-pyrrolo[3,4-d]isoxazol-4-ones derived from the corresponding bicyclic dihydroisoxazoles.
