[2,3]-Wittig sigmatropic rearrangement of γ-allyloxy-β-enaminoesters
Pévet, Isabelle,Meyer, Christophe,Cossy, Janine
, p. 663 - 666 (2003)
The dianions derived from γ-allyloxy-β-enaminoesters undergo a [2,3]-Wittig sigmatropic rearrangement leading to γ-hydroxy-β-enaminoester derivatives, which can be subsequently lactonized to the corresponding 4-aminofuran-2(5H)-ones.
