C. Vanucci et al., TANDEM ZINC MEDIATED REDUCTIVE CLEAVAGE REDUCTIVE AMINATION AS A NEW APPROACH TO SUBSTITUTED PYRROLIDINES FROM HOMOALLYLIC AMINES, Tetrahedron letters, 36(17), 1995, pp. 2971-2974
N-Boc or N-Cbz homoallylic amines are converted in four steps into pyr
rolidines through a sequence involving as a key-step a tandem zinc med
iated reductive cleavage-reductive amination from an intermediate 1,3-
oxazin-2-one
