THERMAL O -> C REARRANGEMENT OF N-PHENYL-ALLYLIMIDATES
Metz, P.,Mues, C.
, p. 6841 - 6854 (2007/10/02)
Properly substituted N-phenyl-allylimidates 1 are shown to undergo preferential O -> C sigmatropic rearrangement on heating.The diastereoselectivity of this reaction resembles the one observed in ortho ester Claisen rearrangements.
