An unprecedented sequential [3+3]/[3+3] annulation of allenoates and dienes catalyzed by phosphine has been developed, which provides novel and facile access to highly functionalized hydroisoquinoline derivatives. The reaction features a wide reaction scope and mild reaction conditions. δ-sulfonamido-allenoates, acting as a five-atom unit, represent a new synthon in the reactions of allenoates.
