Synthesis of Eupolauridine and Its Benzo-Annulated Derivative
摘要:
The unique diazafluoranthene alkaloid eupolauridine (1) was synthesized by a three-step route utilizing as the initial step the thermal rearrangement of the oxime O-crotyl ether 12, which afforded onychine (2). Bracher pyridine synthesis procedure subsequently converted 2 into 1. On the other hand, Friedlander reaction was employed for the synthesis of 3, which is a benzo-annulated derivative of eupolauridine (1).
