    An efficient synthesis of o-terphenyls from Morita–Baylis–Hillman adducts of cinnamaldehydes: a consecutive bromination, Wittig reaction, 6π-electrocyclization, and an aerobic oxidation process
    摘要:
    An efficient synthetic method of o-terphenyls was developed from Morita-Baylis-Hillman adducts. The synthesis was carried out via a sequential bromination of MBH adducts, Wittig reaction with various aldehydes, 6 pi-electrocyclization, and a base-mediated aerobic oxidation process.

  • Diastereoselective synthesis of α-(aminomethyl)-γ-butyrolactones via a catalyst-free aminolactonization

  • Correlation between p<i>K</i><sub>a</sub> and Reactivity of Quinuclidine-Based Catalysts in the Baylis−Hillman Reaction:  Discovery of Quinuclidine as Optimum Catalyst Leading to Substantial Enhancement of Scope
    作者:Varinder K. Aggarwal、Ingo Emme、Sarah Y. Fulford
    DOI:10.1021/jo026671s
    日期:2003.2.1
    powerful combination of quinuclidine with methanol was tested with a host of aldehydes and Michael acceptors. Not only were the reactions more efficient and faster than previously reported, but now new substrates that were previously unreactive could be employed. Notable examples include the use of acetylenic aldehydes and the employment of vinyl sulfones, acrylamides, delta-lactones, and even alpha
    在Baylis-Hillman反应中,已研究了多种基于奎尼丁的催化剂的反应性,并且毫无例外地已确定了碱的碱性和反应性之间的直接相关性。用括号中给出的共轭酸的pK(a)(在水中测量)建立了以下反应顺序:奎尼丁(11.3),3-羟基奎尼丁(9.9),DABCO(8.7),3-乙酰氧基奎尼丁(9.3) ,3-氯喹核苷(8.9)和奎宁环酮(7.2)。通过比较DABCO和3-乙酰氧基奎宁在DMSO中的相对碱性,分析了基于pK(a)的DABCO高于预期的反应性。发现在非质子溶剂中,DABCO的碱性比3-乙酰氧基喹核苷高0.6 pK(a)单位,因此在胺的pK(a)及其反应性之间建立了直接联系。与先前报道相反的文献工作相反,发现具有最高pK(a)的奎尼丁是最活泼的催化剂。与奎尼丁的反应曲线显示出显着的自催化作用,这表明质子供体的存在可能进一步提高速率。因此,研究了一系列带有极性XH键的添加剂,发现甲醇,三
  • Palladium-catalyzed synthesis of indane and cyclobuta[a]indenes from homoallylic alcohols derived from Baylis–Hillman adducts: base-dependent stereoselectivity for the benzylidene group in cyclobuta[a]indene

    DOI:10.1016/j.tet.2011.03.070
    日期:2011.5
    Various indane and cyclobuta[a]indene derivatives were synthesized by palladium-catalyzed cyclization of homoallylic alcohol derivatives prepared from Baylis–Hillman adducts. Especially, cyclobuta[a]indene derivative was synthesized stereoselectively by palladium-catalyzed 5-exo-trig/4-exo-trig cascade cyclization, albeit in moderate yield. The Z isomer was formed exclusively in the presence of Et3N

  • Microwave-assisted synthesis of the (E)-α-methylalkenoate framework from multifunctionalized allylic phosphonium salts
    作者:Lidiane Meier、Misael Ferreira、Marcus M. Sá
    DOI:10.1002/hc.21001
    日期:——
    A convenient and general microwave-assisted method for the synthesis of stereochemically defined α-methylalkenoic acids and esters from allylic phosphonium salts in a basic aqueous medium is described. A selective preparation of acids or esters was dependent on the base (NaOH or NaHCO3) employed in the reaction and could be achieved with good to excellent yields under mild conditions in the absence

  • Organocatalyzed Decarboxylative Trichloromethylation of Morita-Baylis-Hillman Adducts in Batch and Continuous Flow
    作者:Martin V. Enevoldsen、Jacob Overgaard、Maja S. Pedersen、Anders T. Lindhardt

    日期:2018.1.24
    Two protocols for the organocatalyzed decarboxylative trichloromethylation of Morita–Baylis–Hillman (MBH) substrates have been developed. Applying sodium trichloroacetate, as the trichloromethyl anion precursor, in combination with an organocatalyst and acetylated MBH‐alcohols, the desired trichloromethylated products were obtained in good yields at room temperature in batch. The method was next extrapolated
    已经开发出两种用于Morita–Baylis–Hillman(MBH)底物的有机催化脱羧三氯甲基化的方案。将三氯乙酸钠作为三氯甲基阴离子的前体,与有机催化剂和乙酰化的MBH-醇结合使用,可以在室温下分批批量获得所需的三氯甲基化产物。接下来将该方法外推到两步连续流方案中,直接从MBH醇开始,与同时用作碱和催化剂的三丁胺结合使用。事实证明,该流动过程优于分批方法,将反应时间从16小时减少到仅20分钟,并且所有调查项目的收率均得到提高。还采用了两个示例来扩大流量,以产生超过10克的两个三氯甲基化靶标。最后,2 PHAL或(DHQD)2 PHAL在反应中诱导手性转移至生成的立体中心,并具有接近90%ee的选择性 。
