  Inter- and intramolecular Mitsunobu reaction based approaches to 2-substituted chromans and chroman-4-ones

  摘要：

  Two approaches to optically active 2-substituted chromans and chrornan-4-ones are described. The first utilized an intermolecular Mitsunobu reaction of a homochiral halopropanol and 2-bromophenol followed by cyclization to the 2-substituted chroman. In addition, a double lithiation procedure was developed to introduce additional functionality to the chroman. The second approach utilized an intramolecular Mitsunobu cyclization to give the 2-substituted chroman-4-one nucleus. The methodologies were applied to the syntheses of several biologically active natural and synthetic products. (c) 2005 Elsevier Ltd. All rights reserved.

• Gold-Catalyzed Ethynylation of Arenes
  作者：Teresa de Haro、Cristina Nevado

  DOI：10.1021/ja909726h

  日期：2010.2.10

  A novel gold-catalyzed ethynylation of aromatic rings with electron-deficient alkynes via gold catalyzed C-H activation of both C(sp)-H and C(sp(2))-H bonds has been developed. This transformation provides aromatic propiolates difficult to prepare by other methods, highlighting the synthetic potential of gold chemistry.

  Two approaches to optically active 2-substituted chroman-4-ones are described. The first utilized the oxidation of a preformed chroman ring and the second an intramolecular Mitsunobu cyclization. The methodology was applied to the synthesis of the biologically active natural product (−)-pinostrobin (18).

• Synthesis of 2-(o-hydroxyaryl)-4-arylthiazoles by regioselective Pd(0)-catalyzed cross-coupling
  作者：Thorsten Bach、Stefan Heuser

  DOI：10.1016/s0040-4039(00)00018-6

  日期：2000.3

  The difunctional substrate 2,4-dibromothiazole 2 was transformed into the title compounds 1 by consecutive Pd(0)-catalyzed cross-coupling reactions. Aryl zinc reagents which were prepared by ortho-lithiation of compounds 3 and subsequent transmetalation were used as carbon nucleophiles in the first coupling reaction. By this means, an aryl substituent was attached to the 2-position (50-62% yield). A succeeding cross-coupling with arylboronic acids 4 occurred at the 4-position of the intermediate 4-bromothiazoles 5 (76-97% yield). (C) 2000 Elsevier Science Ltd. All rights reserved.
