  Novel palladium-catalyzed synthesis of 1,2-dihydro-4(3H)-carbazolones

  摘要：

  Two sequential palladium-catalyzed reactions are the key steps in a novel synthetic route to carbazolones, an intermolecular Stille coupling followed by a recently developed palladium-catalyzed reductive N-heteroannulation. A number of functionalized 1,2-dihydro-4(3H)-carbazolones were prepared using this sequence. (C) 2002 Elsevier Science Ltd. All rights reserved.

• Catalytic Asymmetric [4 + 2] Cycloadditions and Hosomi–Sakurai Reactions of α-Alkylidene β-Keto Imides

  DOI：10.1021/ol303381c

  日期：2013.2.15

  Highly enantioselective catalytic asymmetric reactions of rationally designed α-alkylidene β-keto imides are described. The [4 + 2] cycloadditions and Hosomi–Sakurai reactions of α-alkylidene β-keto imides proceed with high enantioselectivity and yield. The [4 + 2] cycloadditions of the imides with various dienes afford products bearing an all-carbon quaternary stereogenic center at the ring junction

• General Methodology for the Preparation of Unsymmetrical α-Linked Bisenones via Ligandless Cross-Coupling Reactions
  作者：David R. Williams、Seth A. Bawel

  DOI：10.1021/acs.orglett.7b00497

  日期：2017.4.7

  A stereocontrolled Stille cross-coupling reaction, involving the use of Pd2dba3, provides a general procedure for the synthesis of unsymmetrical α-linked bisenone systems. The transformation is achieved in the absence of phosphine ligands under conditions that promote the stabilization of “ligandless” palladium catalysis. The extension of these studies illustrates Suzuki–Miyaura reactions of 2-bor

  日期：2003.8

  Two sequential palladium-catalyzed reactions are the key steps in a novel synthetic route to 1,2-dihydro-4(3H)-carbazolones. The steps are an intermolecular Stille cross-coupling followed by a reductive N-heteroannulation. A formal total synthesis of murrayaquinone A, employing this sequence, is reported.

  The preparation of imides via the palladium-catalyzed coupling reaction of organostannanes is described. The palladium-catalyzed coupling reaction of aryl-, heteroaryl-, and alkenyl(tributyl)stannanes with methyl N-[methoxy(methylthio)methylene]carbamate in the presence of Cu(I) thiophene-2-carboxylate (CuTC) affords imino ethers, which are converted to the corresponding imides in high yield through acid hydrolysis.
