    One-Step Assembly of Functionalized Morpholinones and 1,4-Oxazepane-3-ones via [3 + 3]- and [3 + 4]-Annulation of Aza-Oxyallyl Cation and Amphoteric Compounds
    摘要:
    A new [3 + 3]- and [3 + 4]-annulation strategy involving azaoxyallyl cation and [1,m]-amphoteric compounds (m = 3,4) is presented. This concise method enables easy assembly of functionalized saturated N-heterocycles, comprised of six-and seven-membered rings and is of high significance in the context of drug discovery approaches. This reaction also represents a new trapping modality of the azaoxyallyl cation with amphoteric agents of different chain lengths that consist of a heteroatom nucleophilic site and a pi-electrophilic site.

  • Diastereoselective Total Syntheses of (±)‐Caseabalansin A and (±)‐18‐Epicaseabalansin A via Intramolecular Robinson‐type Annulation

    日期:2019.6.14
    diastereoselective total syntheses of (±)‐caseabalansin A (1) and (±)‐18‐epicaseabalansin A (2) are described in this paper. We revealed that the intramolecular Robinson‐type annulation of an alkynone was effective in the stereocontrolled construction of the bicyclic skeleton of 1 and 2. Further transformation of the resulting enone, including diastereoselective reduction by LiAlH(OtBu)3, hydroxy‐group‐directed
    本文描述了(±)–caseabalansin A(1)和(±)‐18-picaseaseabalansin A(2)的非对映选择性全合成。我们揭示了炔内酯的分子内罗宾逊型环法在双环骨架1和2的立体控制结构中是有效的。所得烯酮的进一步转化,包括通过LiAlH(O t Bu)3的非对映选择性还原,羟基定向的氢化作用,环化形成环状缩醛部分以及通过C(sp 3)-C()引入侧链sp 3)斯蒂勒偶联反应,合成了(±)-1和(±)-2。
