We describe a useful novel approach to the synthesis of aporphinoids, including dehydroaporphines, aristolactams, 4,5-dioxoaporphines, and 7-oxoaporphines, by means of intermolecular benzyne cycloaddition (IBC). Specifically, we report the total synthesis of the isoquinoline alkaloids norcepharadione B, cepharadione B, dehydroanonaine, duguenaine, dehydronornuciferine, pontevedrine, O-methylatheroline, lysicamine, and alkaloid PO-3.

We describe the radical cyclization of bromobenzylisoquinolines and benzylisoquinolin-3-ones, which afford aporphines or the novel 5-oxoaporphines and 5-oxodehydroaporphines respectively. Oxidation of the latter compounds provides a new route to 4,5-dioxoaporphines.
