A brief total synthesis of fumaramidine

The first total synthesis of the alkaloid fumaramidine is reported. The synthetic tactics involve the sequential construction of the isoindolinone template by a Parham cyclization process followed by benzylic lactam deprotonation, interception with the suitable carboxaldehyde and ultimate E1cb elimination. Final N-lactam deprotection completes the synthesis of the Z configured title compound.
