The total synthesis of lyconadin A from (R)-5-methylcyclohex-2-enone was accomplished. Our synthesis features the facile construction of a highly fused tetracyclic compound through a combination of an aza-Prins reaction and an electrocyclic ring opening. Transformation of the bromoalkene moiety in the tetracycle could be achieved by either a vinylogous Pummerer rearrangement or the formation and subsequent isomerization of the nitrosoalkene to furnish an alpha,beta-unsaturated ketone, from which the pyridone ring was constructed.
