Abstract
|
|
|
|
An enantioselective approach toward the synthesis of the spiroalkaloid (-)-nitramine was achieved by electrophile-induced cyclization of a suitably substituted and protected chiral alpha-allylcyc lohexanecarboxaldi mine. Its hydride-promoted ring expansion after spirocyclization gave rise to the competitive formation of isomeric spiropyrrolidines and a spiropiperidine, the latter being further transformed into (-)-nitramine. |
