D. Kim et al., AN ASYMMETRIC-SYNTHESIS OF (-ISONITRAMINE BY TRIPLE ALLYLIC STRAIN-CONTROLLED INTRAMOLECULAR S(N)2' ALKYLATION()), Tetrahedron letters, 37(9), 1996, pp. 1433-1434
The spirocyclic alkaloid (+)-isonitramine (1) has been synthesized in
a stereo selective manner utilizing a novel 'triple allylic strain-con
trolled' intramolecular lactam enolate S(N)2' alkylation.
