    Formation of N-Heterocycles from 1,1-Diethoxy-5-hydroxyalk-3-yn-2-ones
    摘要:
    When treated with hydrazine, guanidine, and hydroxylamine, 1,1-diethoxy-5-hydroxyalk-3-yn-2-ones undergo Michael addition and give the corresponding beta, beta-disubstituted alpha, beta-unsaturated olefinic ketones, which are unstable and undergo secondary reactions to form heterocyclic compounds. Hydrazine affords 3,5-disubstituted pyrazoles and hydroxylamine 5-hydroxy-4,5-dihydroisoxazoles in very good yields. Guanidine, however, furnishes complex reaction mixtures, which include the corresponding 2-aminopyrimidines. These results show that cyclization involves attack of the ketone moiety by the bisnucleophile reactive terminal group and not the hydroxyl group present in the starting material.

  • Toward the Synthesis of Modified Carbohydrates by Conjugate Addition of Propane-1,3-dithiol to<i>α</i>,<i>β</i>-Unsaturated Ketones

    various conditions. The unprotected hydroxy ketones underwent cyclization during the dithiol addition and gave the corresponding 3‐(diethoxymethyl)‐2‐oxa‐6,10‐dithiaspiro[4.5]decan‐3‐ols 5 in 80–90% yield as the only products (Scheme 3 and Table 1). These products can be regarded as partly modified carbohydrates in the furanose form. When the benzyl‐protected analogues 10‐Bn of the 1,1‐diethoxy‐5‐hydroxypent‐3‐yn‐2‐one

    reaction with secondary amines followed by treatment with acid in a mixture of THF and water. The stability of the furfurals depends to some extent on the nature of the amino group, whereas the reactivity has been shown to be reagent-dependent. When treated with phosphorus ylids, the expected alkenes are formed with E configuration in high yields, but when exposed to nitroalkanes under basic conditions
    通过与仲胺反应,然后在THF和水的混合物中用酸处理,已将γ-羟基α,β-不饱和炔基酮转化为4-氨基取代的糠醛。糠醛的稳定性在一定程度上取决于氨基的性质,而反应性已显示出是试剂依赖性的。当用磷化氢处理时,预期的烯烃以高收率形成E构型,但是当在碱性条件下暴露于硝基烷烃(亨利反应)时,尽管发生收率低,但似乎会发生异常转化,并获得了2-酰化的呋喃,而不是硝基烷醇。

    Abstract α,β-Unsaturated acetylenic γ-hydroxyketones have been shown to react with ethyl acetoacetate in a Michael-addition fashion and subsequently undergo cyclization followed by dehydration to give substituted furans with a predictable regiospecificity. The yields were good to excellent. A mechanism for the transformation is proposed, and this mechanism explains why furan formation does not take
