    摘要:
    我们在这里描述了CrCl(2)促进的α,β-不饱和酰胺的环丙烷化。该反应可以在其中CC双键被二,三或四取代的(E)-或(Z)-α,β-烯酰胺上进行。在所有情况下,该过程都是完全立体定向的,并且仅获得单个非对映异构体。另外,通过使所获得的环丙烷甲酰胺(衍生自吗啉)与一定范围的有机锂化合物反应,可以容易地制备环丙基酮。已经提出了解释环丙烷化反应的机理。

    Synthesis of (E)-α,β-Unsaturated Amides with High Selectivity by Using Samarium Diiodide
    摘要:
    Stereoselective beta -elimination of 2-chloro-3-hydroxyamides 1 is achieved by using samarium diiodide to yield alpha,beta -unsaturated amides 2, in which the C=C bond is di- tri-, or tetrasubstituted. The starting compounds a are easily prepared by reaction of the corresponding lithium enolates of alpha -chloroamides with aldehydes or ketones at -78 degreesC. The influence of the reaction conditions and the structure of the starting compounds on the stereoselectivity of the beta -elimination reaction is also discussed.

    A convenient highly stereoselective synthesis of chloro- and bromocyclopropanamides from di- tri- or tetrasubstituted (E)- or (Z),β-unsaturated amides with total or high stereoselectivity promoted by chromium dichloride or dibromide is described. The transformation of chlorocyclopropanamides into the corresponding ketones or amines is also reported. A mechanism to explain these transformations is

    (Z)-alpha,beta-enamides in which the C-C double bond is di-, tri-, or tetrasubstituted. In all cases the process is completely stereospecific and only a single diastereoisomer is obtained. In addition, cyclopropyl ketones were readily prepared by reaction of the cyclopropanecarboxamides (derived from morpholine) obtained with a range of organolithium compounds. A mechanism has been proposed to explain the cyclopropanation
