    摘要:
    用氢碘酸处理2-烷基烯烃环酮,并在苯中进行反应,随后用锌粉在四氢呋喃中,在三甲基氯硅烷或四氯化钛三异丙基氧化物的存在下与所得到的β-碘酮反应,得到了高产率的外型和内型(n+3)-烷基双环[n.1.0]烷-1-醇。在这些条件下,中间体β-碘酮的环化反应表现出适度到良好的非对映选择性,所得到的双环环丙醇可以通过硅胶柱层析轻松分离。这种方法获得的外型7-异丙基双环[4.1.0]庚醇被有效地用作辣椒素合成中的关键中间体。

  • Catalytic [4+1] Cycloaddition of α,β-Unsaturated Carbonyl Compounds with Isocyanides
    作者:Masayuki Oshita、Kohei Yamashita、Mamoru Tobisu、Naoto Chatani
    DOI:10.1021/ja0450206
    日期:2005.1.1
    substrates having a bulky substituent, such as a tert-Bu group, at the beta-position give high yields. Bulkiness is also required in cyclic alpha,beta-unsaturated ketones, but the effect is small. In alkyl vinyl ketones, the reactivity decreased with the steric bulk of the alkyl group. In aryl vinyl ketones, the presence of an electron-donating group on the aromatic ring decreases the reactivity. The
    描述了 GaCl(3)-催化的 [4+1] 环加成反应,α、β-不饱和酮与异氰化物导致内酯衍生物。虽然其他一些路易斯酸也显示出催化活性,但 GaCl(3) 是最有效的催化剂。该反应受异氰化物和 α,β-不饱和酮的结构影响很大。可以使用芳香族异氰化物,特别是空间要求高的异氰化物和带有吸电子基团的异氰化物,但脂肪族异氰化物不能使用。无环α,β-不饱和酮的β-位取代基的体积是反应有效进行的重要因素。通常,庞大的取代基越多,产率越高。α的反应,在β-位带有孪生取代基的β-不饱和酮以高产率得到相应的产物。在单取代衍生物中,产率相对较低。然而,在 β 位具有大取代基(例如叔丁基)的底物会产生高产率。环状α,β-不饱和酮也需要体积大,但影响很小。在烷基乙烯基酮中,反应性随着烷基的空间体积增大而降低。在芳基乙烯基酮中,芳环上存在给电子基团会降低反应性。与通常的路易斯酸相比,催化的成功可归因于 GaCl(3)
