The novel reagents formed by combination of allylmagnesium chloride and a strong non-nucleophilic lithium base (LiNR2) convert non- or slowly enolizable carboxylic esters or carboxamides into 2-propenyl ketones which are protected from further reaction by their in situ conversion into enolates.This modified Grignard reaction is applied to efficient syntheses of α-damascone, β-damascone, β-damascenone, and various other (E)-1-propenyl ketones.
