  Diversity-Oriented Construction of Highly Substituted Indolizinones

  摘要：

  Rapid generation of small library of highly functionalized indolizonones was realized by exploiting three palladium-catalyzed cross-coupling reactions of 2-iodoindolizinones which in turn were readily accessed via sequential iodine-mediated cyclization/1,2-shift reactions of propargylic alcohols.

  A highly efficient catalyst-free synthetic route to indoli­zinones was established from readily available tertiary propargylic alcohols via a facile thermally induced cycloisomerization. In addition, this transformation was found to be further expedited by microwave irradiation.

  以易得的叔炔醇为原料，通过简单的热诱导环异构化，建立了一种高效的无催化剂合成吲哚嗪酮的路线。此外，还发现微波辐射进一步加速了这种转变。

  We have developed a highly efficient one-pot approach to poly-substituted indolizinones from tertiary propargylic alcohols by using a palladium-catalyzed domino reaction. This reaction is proposed to proceed via successive aminopalladation, reductive elimination, and 1,2-shift. While our previous effort to the same skeleton via 2-iodoindolizinones selected alpha,beta-unsaturated esters, terminal acetylenes, or boronic acids as coupling partners, this strategy introduces new functional groups at the C2 position of indolizinone core with (hetero)aryl halides or diallyl carbonate, expanding the substrate scope for decoration at the C2 site. Furthermore, a new preparation route to tertiary propargylic alcohols for this study is described to rapidly diversify the molecular framework. (c) 2012 Elsevier Ltd. All rights reserved.
