An (E)-selective synthesis of trisubstituted (E)-α, β-unsaturated acid derivatives

Feuillet, Fred J. P.,Robinson, Diane E. J. E.,Bull, Steven D.

, p. 2184 - 2185 (2003)

Potassium alkoxides of N-acyloxazolidin-2-one derived synaldolates undergo a novel tandem intramolecular cyclisation elimination reaction to afford trisubstituted (E)-α,β-unsaturated amides in high d.e., which may be converted into their corresponding acids or oxazolines in good yield.
