  Application of the intramolecular PIFA-mediated amidation of alkynes to the synthesis of substituted indolizidinones

  摘要：

  The construction of the title compounds has been achieved from properly substituted linear alkynylamides through the suitable combination of two key cyclization steps. First, an intramolecular PIFA-mediated alkyne amidation protocol leads to the creation of the pyrrolidinone nucleus, which under proper manipulation of the generated keto carbonyl group permits the assembling of the indolizidinone skeleton by the introduction of a subsequent ring closing olefin metathesis step. Finally, its transformation into a series of substituted mono- and trihydroxylated indolizidinone derivatives is achieved by manipulation of the remaining unsaturated fragment under hydrogenation and dihydroxylation conditions.

  A novel domino reaction, alkyne-mediated domino hydroformylation/double cyclization, has been developed for rapid preparation of indolizidine type alkaloids. DFT calculations were applied for rationales of reactivity and selectivity. A concise synthesis of tashiromine as the application of the methodology is also reported.

  A domino method for the rapid syntheses of 1‐azabicyclo[x.y.0]alkane scaffolds, such as indolizidines, quinolizidines, decahydropyridoazepines, and their derivatives, has been developed. This strategy involved a rhodium‐catalyzed hydroformylation of allyl‐, 3‐butenyl‐, or homoallyl amides, followed by two spontaneous ring closures under mild conditions. The reaction scope and diastereoselectivity were

  已经开发了一种用于快速合成1-氮杂双环[ xy .0]烷烃骨架的多米诺骨牌方法，这些骨架包括吲哚并立兹，喹唑嗪，十氢吡啶并ze庚因及其衍生物。该策略涉及烯丙基，3-丁烯基或高烯丙基酰胺的铑催化加氢甲酰化，然后在温和条件下进行两个自发的闭环反应。通过改变酰胺上的取代方式和改变碳链的长度，可以充分探索反应范围和非对映选择性。该方法用于天然生物碱他四郎胺和表柔比林的合成。两种异构酰胺底物3-丁烯酰胺1 j和高烯丙基酰胺1 i的反应性之间存在明显差异可以归因于在环化过程中从丁烯酰胺衍生而来的过渡态中更好的HOMO-LUMO重叠。DFT计算支持该解释。

  日期：2007.2.1

  The hypervalent iodine reagent PIFA promotes the intramolecular electrophilic cyclization of easily accessible alkynylamides and alkynyl carboxylic acids, leading to the formation of pyrrolidinone and lactone skeletons, respectively, in a very efficient way. A synthetic study and a mechanistic proposal for these transformations are presented.
