    Toward the Synthesis of Biologically Important Chlorins, Isobacteriochlorins, and Corrins. Cyclic Enamides from Acetylenic Amides
    摘要:
    Cyclic enamides 1 of a type useful in the synthesis of naturally occurring chlorins, isobacteriochlorins, and corrins have been prepared by a process involving 5-exo-dig cyclization of the appropriate acetylenic amides 11. The desired cyclization is catalyzed by either n-Bu(4)NF or LiAl-(NHBn)(4).

    摘要:
    描述了一种新的合成硫内酯的方法,该方法在非常温和的条件下采用有效的酰基硫醇-烯(ATE)或酰基硫醇-炔(ATY)环化反应将不饱和硫代羧酸衍生物转化为硫代内酯。这些反应过程的高总收率,快速动力学,高非对映选择性,出色的区域控制以及广泛的底物范围,使其成为面向多样性的合成和药物开发工作的非常有用的方法。为观察到的区域控制提供了详细的计算原理。

  • A highly active diradical cobalt(<scp>iii</scp>) catalyst for the cycloisomerization of alkynoic acids
    作者:Nicolas Leconte、Amaury du Moulinet d'Hardemare、Christian Philouze、Fabrice Thomas
    DOI:10.1039/c8cc04459g
    日期:——
    The first cobalt-catalysed cycloisomerisation of alkynoic acids is reported, thanks to the design of a well-defined diradical cobalt(III) catalyst, in the absence of any additives. The high efficiency, regioselectivity and chemoselectivity are comparable to those of noble metal-based systems. The unique reactivity might be attributed to second coordination sphere effects.
    据报道,由于在没有任何添加剂的情况下设计了定义明确的双自由基钴(III)催化剂,首次进行了钴催化的炔酸环异构化反应。高效,区域选择性和化学选择性可与基于贵金属的系统相媲美。独特的反应性可能归因于第二协调领域效应。

  • Cyclization of alkynoic acids with gold catalysts: a surprising dichotomy between AuI and AuIII
    作者:Hassina Harkat、Albert Yénimégué Dembelé、Jean-Marc Weibel、Aurélien Blanc、Patrick Pale
    DOI:10.1016/j.tet.2008.10.112
    日期:2009.2
    ω-Acetylenic acids, substituted or not at their acetylenic end, could be efficiently cyclized to γ- or δ-alkylidene lactones in the presence of AuCl and K2CO3. In contrast AuCl3 led to lactone dimers, probably through cyclization and reductive dimerization. These AuI and AuIII catalyzed cyclizations were totally regioselective and most often highly stereoselective.
    在AuCl和K 2 CO 3的存在下,可以在其乙炔基末端取代或不取代的ω-乙炔酸有效地环化为γ-或δ-亚烷基内酯。相反,AuCl 3可能通过环化和还原性二聚而导致内酯二聚体。这些Au I和Au III催化的环化反应完全是区域选择性的,并且通常是高度立体选择性的。
