Development of a concise construction of the pentacyclic core skeleton of isoschizogamine was described. Tetracyclic A,B,D,F-rings structure was assembled by intramolecular aza-Diels–Alder reaction via an ortho-iminoquinone methide intermediate. The C-ring was formed by oxidation of the benzylic position with a combination of Cr(CO)6 and t-BuOOH, followed by the introduction of an aminoethyl side chain, C–H oxidation of the lactam ring with CrO3 and n-Bu4NI, and final cyclization to construct the cyclic aminal moiety.
