Efficient synthesis of β'-amino-α, β-unsaturated ketones

Abrunhosa-Thomas, Isabelle,Plas, Aurelie,Kandepedu, Nishanth,Chalard, Pierre,Troin, Yves

, p. 486 - 495 (2013/04/23)

A general and simple procedure to access chiral β'-amino-α, β-enones, in seven steps, from an α,β unsaturated ester has been described. The use of a Horner-Wadsworth-Emmons reaction as a key step for generating the β'-amino-α,β-enones, permits access to a range of substrates under mild conditions and in moderate to high yield.
