Jm. Davis et al., CONVERGENT SYNTHESIS OF AMINOBICYCLO[3.3.0]OCTENES USING ZIRCONIUM CHEMISTRY - AN UNUSUAL ANTI-1,3-AMINE SHIFT, Synlett, (2), 1994, pp. 110-112
Insertion of phenyl isocyanide into zirconacyclopentenes affords imino
acyl complexes which rearrange to give alpha,beta-unsaturated zirconoc
ene eta2-imine complexes. These insert alkenes or alkynes to afford el
aborated cyclopentenylamines on protic work-up. The products undergo a
facile anti-1,3-amine-shift to afford 1-anilinobicyclo[3.3.0]oct-2-en
es.
