Ja. Wendt et J. Aube, TOWARD THE SYNTHESIS OF SPARTEINE - INTRAMOLECULAR SCHMIDT REACTIONS ON A NORBORNANONE PLATFORM, Tetrahedron letters, 37(10), 1996, pp. 1531-1534
The intramolecular Schmidt reaction was applied to the norbornane skel
eton to examine an approach to sparteine. In so doing, the stereospeci
ficity of intramolecular Schmidt reactions of epsilon-azido ketones wa
s demonstrated. The intramolecular Schmidt reaction was found to fail
in a ketone containing a lactam moiety.
