  Synthesis of 2,3,5-trisubstituted furans from α-formylaroylketene dithioacetals

  摘要：

  A new strategy for the synthesis of 2,3,5-trisbustituted furans from alpha-formylketene dithioacetals is described. The protocol involves a facile conversion of alpha-formylketene dithioacetals to vinylketene dithioacetals via Wittig reaction and subsequent N-bromosuccinimide-mediated cyclization to 2,3,5-trisbustituted furans. Further conversion of the 2-thioalkylfurans thus obtained to 2-aminofurans shows the potential synthetic utility of this new approach. (c) 2011 Elsevier Ltd. All rights reserved.

  Functionalized 1,3-dienes were efficiently accessed from visible-light-driven, palladium-catalyzed Heck reaction of S,S-functionalized internal vinyl bromides with styrenes under mild conditions. This Heck reaction showcased tolerance of a wide array of functional groups, afforded the target products in moderate to excellent yields through a radical reaction pathway. The resultant diene products could

  功能化的 1,3-二烯可通过可见光驱动、钯催化的S , S-官能化内乙烯基溴化物与苯乙烯在温和条件下的Heck 反应有效地获得。这种 Heck 反应展示了对多种官能团的耐受性，通过自由基反应途径以中等至极好的收率提供目标产物。所得二烯产物可以进一步转化为高度官能化的三取代呋喃衍生物。
