Efficient synthesis of a new structural phenanthro[9,10,3′,4′] indolizidine starting from pyrrole

(Chemical Equation Presented) A new structural phenanthroindolizidine, 2,3,6,7-tetramethoxyphenanthro[9,10,3′,4′]indolizidine, has been synthesized efficiently from pyrrole. An important feature of this synthesis is that intramolecular oxidative coupling

Synthesis of (±)-septicine

The total synthesis of the indolizidine alkaloid, (±)-septicine (5) (27% overall yield) in 8 steps from dimethyl squarate is presented. The key step of the synthesis involves the ring expansion of 2,3-bis-(3,4-dimethoxyphenyl)-4-(1-pyrrolo)cyclobutenone 12 to the corresponding indolizine-5,8-dione 6. The synthesis is highly convergent and thus could be used for the synthesis of a variety of analogs.
