Tandem Cationic aza-Cope Rearrangement−Mannich Cyclization Approach to the Core Structure of FR901483 via a Bridgehead Iminium Ion
摘要:
[GRAPHICS]An approach to the potent immunosuppressant FR901483 is described, This route utilizes a tandem cationic aza-Cope rearrangement-Mannich cyclization to generate the core structure of this compound. In addition, this is the first demonstration of this tandem reaction passing through a bridgehead iminium ion.
