Phosphorus containing Lewis base catalyzed cascade reactions of isatin-derived oximes with allenicesters afford the corresponding functionalized nitrones. Further Lewisacidcatalyzed highly regioselective intramolecular [3+2] cyclizations give the corresponding bridged cycloadducts. Moreover, a combined “one-pot” reaction is also feasible for the above two catalytic reactions.
