  The 1,4-elimination reaction of (Z)-N-Boc-2-(4-methoxy-2-alkenyloxy)pyrrolidines (1) is shown to proceed with high (1E,3E)-stereoselectivity to afford N-Boc-2-(1,3-dienyloxy)pyrrolidines (2); the Brønsted acid catalyzed aza-Ferrier reaction of the N-Boc-2-(1,3-dienyloxy)pyrrolidines (2) provides α-(N-Boc-2-pyrrolidinyl) aldehydes (3) in excellent yields with high α-regioselectivities.

  (Z)-N-Boc-2-(4-甲氧基-2-烯丙氧基)吡咯烷（1）的1,4-消除反应表现出高度的（1E,3E）-立体选择性，生成N-Boc-2-(1,3-二烯氧基)吡咯烷（2）；布朗斯特酸催化的N-Boc-2-(1,3-二烯氧基)吡咯烷（2）的氮杂-费里尔反应在优异的产率下提供了具有高α-区域选择性的α-(N-Boc-2-吡咯烷基)醛（3）。

  Treatment of 1-alkoxy-4-methoxy-(2Z)-alkenes or 1-siloxy-4-methoxy-(2Z)-alkenes with n-butyllithium in diethyl ether is shown to afford the corresponding (1Z,3E)-dienyl, alkyl or silyl ethers, respectively, in high stereoselectivity via a facile 1,4-elimination. The scope and the regio- and stereochemical features of the synthetic method are described.

• Copper-Catalyzed Regiospecific and 1,2-Regioselective Cyclopropanation of (1Z)-1-Amino- and (1Z)-1-Oxy-1,3-butadienyl Derivatives
  作者：Eiji Tayama、Shun Saito

  DOI：10.1055/s-0034-1380426

  日期：——

  The copper-catalyzed regiospecific and 1,2-regioselective cyclopropanation of (1Z)-1-amino- and (1Z)-1-oxy-1,3-butadienyl derivatives, which could be prepared by Z-stereoselective 1,4-elimination with a-aryl diazoesters was successfully demonstrated. This successful regiospecific protocol enabled the preparation of the corresponding 1-amino- and 1-oxy-2-vinylcyclopropane derivatives as almost single stereoisomers.
• Regio- and Stereoselective Ferrier Reaction of <i>O</i>-1,3-Dienyl Acetals Promoted by Organoaluminum Complexes
  作者：Eiji Tayama、Wataru Isaka

  DOI：10.1021/ol062042j

  日期：2006.11.1

  The Ferrier reaction of O-1,3-dienyl acetals promoted by organoaluminum complexes such as methylaluminum bis(2,6-di-tert-butyl-4-methylphenoxide) (MAD) is shown to proceed with a high degree of regio- and stereoselectivity to afford the corresponding alpha-alkenyl-substituted beta-alkoxy aldehydes in good yields. The mechanistic origin of the high regiocontrolling ability of MAD is elucidated. This method, coupled with the easy availability of the requisite substrates, expands the synthetic scope of the Ferrier reaction.

  日期：2016.2

  The regioselective synthesis of secondary 1,3-dienamides 3 (1-N-acylamino-1,3-dienes) is successfully demonstrated by regiospecific base -promoted 1,4 -elimination of (Z)- or (E)-N,N-di-Boc-4-methoxy-2-buten-1 -ylamine 1 followed by mono-Boc elimination in situ.
