• Stereocontrol of stereogenic centres para on a benzene ring using the SE2? reaction of a pentadienylsilane
  作者：Ian Fleming、Colin P. Leslie

  DOI：10.1039/p19960001197

  日期：——

  The pentadienylsilane 9 and the dimethyl acetal 2 of isobutyraldehyde react with high (80:20)anti stereospecificity to give largely the diene 10a, which was converted into the para-disubstituted benzene 11a, having 1,6-related stereogenic centres.

  戊二烯基硅烷 9 和异丁醛的二甲基缩醛 2 以高 (80:20) 反立体定向性反应，主要生成二烯 10a，将其转化为具有 1,6 相关立构中心的对位二取代苯 11a。
• Preparation and reactivity of highly functionalized organometallics at the .alpha. position of oxygen or nitrogen
  作者：Paul Knochel、Tso Sheng Chou、Carole Jubert、Duddu Rajagopal

  DOI：10.1021/jo00055a010

  日期：1993.1

  Alpha-Halogenoalkyl carboxylates (FG-R1CH(X)(OCOR2); FG = COOR, CN, SR; X = I, Br) were readily prepared by the addition of an acid chloride or bromide (R2COX; X = Br or Cl) to an aldehyde (FG-RCHO) in the presence of a catalytic amount of ZnCl2. They insert efficiently zinc dust in THF-DMSO (X = Br, 8-10-degrees-C, 6-10 h) affording the corresponding zinc organometallics at the a position to oxygen FG-RCH(ZnBr)(OAc). After the addition of the THF-soluble copper salt CuCN.2LiCl, the corresponding copper reagents FG-RCH(Cu(CN)ZnBr)(OAc) are formed and reacted with various classes of electrophiles such as acid chlorides, aldehydes, enones, allylic and alkynyl halides, activated alkynes, nitro olefins and alkylidenemalonates providing polyfunctional molecules in excellent yields. Similarly, zinc organometallics at the a position to the nitrogen of cyclic imides were prepared by the zinc insertion to cyclic alpha-chloromethyl (or alpha-chloroethyl) imides. After their transmetalation to the corresponding copper organometallic ((R1CO)2NCH(R)(Cu(CN)ZnCl); R = Me or H), they were reacted with allylic and alkynyl halides and ethyl propiolate affording polyfunctional imides. The reaction of cyclic N-(chloromethyl)imides with aldehydes in the presence of chromium(II) chloride in THF furnishes protected amino alcohols in 36-95% yield.
• Soluble precursors convertible to tetrabenzoporphyrins below room temperature

  日期：2003.7

  Porphyrins fused with dihydroxylated bicyclo[2.2.2]octadiene at beta-positions were quantitatively converted to the corresponding tetrabenzoporphyrins either by treatment with NaH in DMF at 0degreesC or on boehmite at room temperature. (C) 2003 Published by Elsevier Science Ltd.
