  用DIBAL-H还原叔膦氧化物

  摘要：

  详细研究了用二异丁基氢化铝（DIBAL-H）还原叔膦氧化物（TPO）和硫化物。广泛的溶剂筛选表明，受阻脂族醚（例如MTBE）最适合在室温下进行此反应。许多TPO在环境温度下会经历相当大的降低，然后由于抑制作用而失速。31 P和13使用同位素标记的底物进行的13 C NMR研究以及竞争研究表明，这种抑制作用的来源是四异丁基二铝氧烷（TIBAO），随着反应的进行而积累。TIBAO有选择地协调TPO原料，防止进一步减少。已经发现了几种策略来绕开这种抑制作用并首次用这种极其廉价的还原剂获得完全转化。已经为这些关键目标制定了实用的减排方案。

  Palladium-catalysed synthesis of biaryl phosphines

  摘要：

  Monodentate, biphenyl-type phosphines have emerged as a powerful class of ligands in homogeneous catalysis. Synthetic methods for these ligands are limited, however. We report that the palladium-catalysed Suzuki coupling of OPR2(o-C6H4X) (R=Ph, t-Bu; X=Br, I) with arylboronic acids affords a variety of biaryl phosphine oxides including those that contain heterocycles. The corresponding phosphines are readily obtained by treatment with HSiCl3. The methodology provides an easy entry to monodentate biaryl and heterobiaryl P<^>X (X=N, O, S) phosphines with diverse steric and electronic properties. (C) 2004 Elsevier Ltd. All rights reserved.

  Palladium-Catalyzed Intramolecular α-Arylation of α-Amino Acid Esters

  摘要：

  The Pd-catalyzed intramolecular alpha-arylation of alpha-amino acid esters is described. Starting from readily available amino acids, the synthesis of a variety of isoindolines and tetrahydroisoquinoline carboxylic acid esters has been accomplished. Additionally, fused tricyclic systems can be efficiently prepared from cyclic amino acid esters. Reaction conditions have been found that allow the use of tert-butyl ester and N-(benzyloxycarbonyl) protecting groups.

  inhibition is tetraisobutyldialuminoxane (TIBAO), which builds up as the reaction proceeds. TIBAO selectively coordinates the TPO starting material, preventing further reduction. Several strategies have been found to circumvent this inhibition and obtain full conversion with this extremely inexpensive reducing agent for the first time. Practical reduction protocols for these critical targets have been developed
