    Regioselective Alkylations of Cyclic 1,3-Diketonesvia Metalated Dimethylhydrazones
    摘要:
    Cyclic 1,3- diketones 1 are transformed into their 2,2-dimethylhydrazones 2, which can be alkylated regioselectively at different positions after mono-, di-, tri-, and tetrametalation. Monometalated C-2 unsubstituted hydrazones afford C-2 and N-alkylation, monometalated C-2 substituted hydrazones afford only C-2 alkylation. The regioselectivity of the alkylation of the polymetalated hydrazones follows Hauser's rule according to the sequence: NH- > C-4 Ha > C-5 > C-4 Hb. Hydrolysis of the product hydrazones 3-5 afforded mono-and polyalkylated 1,3- diketones 7 in good yields.

    reductive coupling protocol has been developed for the selective high-yielding synthesis of nearly fifty examples of propargylated cyclic/acyclic systems from the various propargyl aldehydes, cyclic/acyclic CH acids, and Hantzsch ester under ambient conditions. It is an economical, efficient, catalytic, metal-free protocol for the quick gram-scale synthesis of propargylated cyclic/acyclic compounds

    preparation through Robinson annulation of enantiopure building blocks with both academic and industrial relevance, such as the Wieland–Miescher and Hajos–Parrish ketones, has suffered from important drawbacks, such as the need for high catalyst loading or extremely long reaction times. Here we report a heterogenized organocatalyst based on Luo’s diamine for fast and broad-scope enantioselective Robinson
    通过罗宾逊环空法制备的具有学术和工业相关性的对映纯净结构单元,例如Wieland–Miescher和Hajos–Parrish酮,存在一些重大缺点,例如需要高催化剂负载量或极长的反应时间。在这里,我们报告基于罗氏二胺的异质有机催化剂,用于快速和广谱对映选择性罗宾逊环化反应。聚苯乙烯负载的二胺19a能够在温和条件下以高收率,高对映选择性制备各种手性双环烯酮,反应时间短至60分钟(间歇),停留时间短于10分钟(流动)。与其均相的对应物19b相反,催化树脂19a在2-MeTHF中随着温度的升高催化活性显着提高(从室温到55°C观察到反应时间减少了10倍,对映选择性没有下降)。批处理模式下的转换范围已通过14个示例进行了说明,其中包括仅以对映体富集不佳(22n)或外消旋形式(22k)报道的示例。Enantiopure 22k已被用作抗生素和拒食倍半萜(-)-异卵磷脂(24)的直接形式合成的起始原料

    作者:Hsiao‐Feng Chen、Ming‐Chang P. Yeh

    A facile synthesis of tetrahydrobenzo[b]furans via gold(I)‐catalyzed cycloisomerization of 1‐aryl2‐propargylcyclohex‐2‐enols is described. The transformation is suggested to proceed through a gold(I)‐catalyzed tertiary allylic alcohol rearrangement to give a secondary allylic alcohol that underwent a 5‐exo‐dig addition of the hydroxyl group onto the gold(I)‐activated alkyne to give a vinylgold species
