  • Organocatalytic Knoevenagel condensation by chiral C<sub>2</sub>-symmetric tertiary diamines

    The asymmetric Knoevenagel condensation of aliphatic aldehydes and active methylene compounds catalyzed by (1S,2S)-1,2-diaminocyclohexane-derived catalysts is presented and investigated.

    对由(1S,2S)-1,2-二氨基环己烷衍生的催化剂催化的脂肪族醛和活性亚甲基化合物的不对称Knoevenagel缩合进行了研究。
  • The Catalytic Asymmetric Knoevenagel Condensation

    116 years after the discovery of the Knoevenagel condensation, the first catalytic asymmetric variant has been developed. Dynamic kinetic resolution in the reaction of α‐branched aldehydes with malonates in the presence of a newly designed and readily available modified cinchona amine catalyst gives the corresponding alkylidene malonates in high enantioselectivity (see scheme).
    在发现Knoevenagel缩合反应116年后,开发了第一个催化不对称变体。在新设计且易于获得的改性金鸡纳胺催化剂存在下,α-支链醛与丙二酸酯反应的动态动力学拆分可得到高对映选择性的相应亚烷基丙二酸酯(参见方案)。
  • Highly efficient thermal cyclization reactions of alkylidene esters in continuous flow to give aromatic/heteroaromatic derivatives

    Intramolecular thermal cyclization and benzannulation reactions of the Gould–Jacobs and Conrad–Limpach types were performed in a designed continuous flow reactor system at temperatures in the range of 300–360 °C and under high pressure conditions (100–160 bar) with very short residence times (0.45–4.5 min) in tetrahydrofuran as a low-boiling point solvent. Substituted heteroaromatic compounds including
    Gould–Jacobs和Conrad–Limpach类型的分子内热环化和苯环化反应在设计的连续流反应器系统中在300–360°C的温度范围内和高压条件下(100–160 bar),非常短的时间内进行在四氢呋喃中作为低沸点溶剂的停留时间(0.45-4.5分钟)。以中等至高收率合成了取代的杂芳族化合物,包括吡啶并嘧啶酮和羟基喹啉。应用反应条件还可以合成萘酚和联苯衍生物。该过程涉及容易的后处理,并且非分批制备的合成方法适合于自动化。
  • 1,2-Asymmetric Induction in the Conjugate Addition of Organocopper Reagents to γ-Aryl α,β-Unsaturated Carbonyl Derivatives
    作者:Yukiyasu Chounan、Yasuo Ono、Shinji Nishii、Haruo Kitahara、Shoei Ito、Yoshinori Yamamoto
    DOI:10.1016/s0040-4020(00)00137-x
    日期:2000.4
    The diastereoselectivity in the conjugate addition of organocopper reagents to γ-aryl α,β-unsaturated carbonyl derivatives 8–14 was investigated. The syn-diastereoselectivity was obtained irrespective of the reagents type in the addition of 8, while the anti-diastereoselectivity was obtained in the addition of 10–14 with RCu and RCu(CN)Li (R=Me and Bu) and the syn-selectivity was produced in the addition
    研究了将有机铜试剂共轭添加到γ-芳基α,β-不饱和羰基衍生物8-14中的非对映选择性。所述顺式得到-diastereoselectivity不论添加8试剂型的,而抗在此外的10-14与RCU和RCU(CN)栗(R =我和丁基)以及得到-diastereoselectivity顺式-通过添加10–14的R 2 CuLi和R 2 Cu(CN)Li 2可以产生选择性。试剂控制的和底物依赖性的非对映选择性是通过两种不同的反应途径来解释的:π络合物的形成或普通的亲核加成。迈克尔受体的还原电势和有机铜试剂的供电子能力控制着反应路径。
