Michael-type reaction of ethyl bromodifluoroacetate with alpha,beta- unsaturated carbonyl compounds in the presence of copper powder.

چکیده
We have reported that the reaction of ethyl bromodifluoroacetate (1) with alkenyl iodides in the presence of copper powder gives ethyl alkenyldifluoroacetates. As an extension of this reaction, reaction of 1 with Michael acceptors in the presence of copper powder was examined and found to give 1,4-addition products selectively, unless the acceptor has a group stabilizing a radical intermediate, such as a phenyl group.

A chiral copper-hydride catalyst for the asymmetric conjugate reduction of alpha,beta-unsaturated carbonyl compounds has been used for the reduction of substrates containing beta-nitrogen substituents. A new set of reaction conditions has allowed for a variety of beta-azaheterocyclic acid derivatives to be synthesized in excellent yields and with high degrees of enantioselectivity. In addition,...

Since the discovery by Knoevenagel [1] that doubly activated carbonic acids (CH-acids) react with carbonyl compounds to give the corresponding conjugated olefins, this reaction has been widely used in organic synthesis as an important method for carbon —carbon bond formation [2, 3). The conden sation of 1,3-dicarbonyl compounds with monocar bonyl compounds usually leads to a,/3-unsaturated pr...
