• Novel<i>ortho</i>-Alkoxy-Substituted Phosphorus Ylides and Their Stereoselectivity in Witting Reactions
  作者：Suruliappa Jeganathan、Masamitsu Tsukarmoto、Manfred Schlosser

  DOI：10.1055/s-1990-26801

  日期：——

  The stereochemistry of the reactions between tris(2-methoxy-methoxyphenyl)phosphonioethanide (1f), -butanide (2f), and -phenyl-methanide (3f) and a variety of aldehydes was investigated. Ylides having a β-unbranched aliphatic sidechain, such as 2f, and saturated straight-chain aldehydes give olefins with unprecedented cis-selectivity (cis/trans ≍ 200:1).

  三(2-甲氧基甲氧基苯基)膦醯電乙烷錘(1f)、-丁烷錘(2f)和-苯甲烷錘(3f)与一系列醛类反应的立体化学被研究了。具有β-无分支脂肪链的叶立德(如2f)和饱和直链醛类产生前所未有的顺式选择性烯烃(顺/反 ≈ 200:1)。

  日期：2003.8.1

  A highly enantioselective, quinone Diels-Alder reaction catalyzed by chiral samarium and gadolinium pyridyl-bis(oxazoline) (pybox) complexes has been developed. The reaction scope has been extended to include three quinones and five dienes, all of which exclusively provide the expected endo product in excellent yields and enantioselectivities.

• Use of α-chlorosulfides in indium promoted CC couplings: easy entry into the stereoselective formation of epoxy alkynes
  作者：Gregory Engstrom、Meisha Morelli、Carolyn Palomo、Thomas Mitzel

  DOI：10.1016/s0040-4039(99)01152-1

  日期：1999.8

  The use of alpha-chlorosulfide compounds to control stereoselectivity in indium promoted C-C couplings occurs smoothly at room temperature under aqueous and mixed aqueous/organic conditions. Use of the halide to control syn/anti ratios simplifies the indium promoted coupling with respect to earlier studies and is used to gain entry into stereocontrolled epoxy alkynes in good yields.
