    α,β-Unsaturated esters and amides were conveniently obtained from the trialkylstibine-promoted reaction of α-halogenocarboxylic derivatives with carbonyl compounds. In this reaction, a quaternary stibonium salt is an active intermediate that can be trapped and can undergo further reaction with the substrate.

    An efficient chromium-promoted alkyl- or silylcyclopropanation of α,β-unsaturated amides is described. These reactions can be carried out on (E)- or (Z)-α,β-enamides in which the C−C double bond is di-, or trisubstituted. This process takes place with total stereospecificity and the new stereogenic center is generated with high or total stereoselectivity. Some synthetic applications of the obtained

  • Sequential Reactions Promoted by Manganese:  Completely Stereoselective Synthesis of (<i>E</i>)-α,β-Unsaturated Amides, Ketones, Aldehydes, and Carboxylic Acids
    作者:José M. Concellón、Humberto Rodríguez-Solla、Pamela Díaz
    DOI:10.1021/jo701417z
    日期:2007.10.1
    A complete E-selective synthesis of a,alpha,beta-unsaturated amides through a sequential reaction of a range of dichloroamides with a variety of aldehydes promoted by Rieke manganese (Mn*) is reported. A mechanism based on a sequential aldol-type reaction and a completely stereoselective beta-elimination is proposed to explain these results. The unsaturated amides obtained are readily and efficiently transformed into alpha,beta-unsaturated ketones, aldehydes, or carboxylic acids without loss of the diastereoisomeric purity of the C-C double bond.
