  Alkylation of allylic derivatives. 17. Cross-coupling reactions of diallylic pivalates with butyl- and phenylcopper reagents

  摘要：

  Cross coupling (Z)-1-phenyl-1,4-pentadien-3-yl pivalate (cis-1-OPiv) with LiCuBu2, LiCu(CN)Bu, LiCuPh2, and LiCu(CN)Ph gives only the fully conjugated gamma-coupling product. With LiCuBu2, substantial loss of double-bond configuration occurs to give primarily the all-trans coupling product. With other cuprates, no detectable loss of double-bond configuration was observed. Cross coupling (Z)-3-(2-phenylethenyl)2-cyclohexen-1-yl pivalate (cis-18-OPiv) with LiCuBu2, LiCuPh2, and LiCu(CN) ph gives only alpha-coupling product; with LiCu(CN)Bu, a mixture of alpha, gamma, and epsilon coupling product was obtained. Cross coupling with LiCuBu2, results in loss of double-bond configuration in the alpha-alkylation product. With the other cuprates, no loss of double-bond configuration was detected in the alpha and gamma coupling product. These results have profound mechanistic implications, which are discussed. The relationship between structure and reactivity was also investigated. A variety of diallylic pivalates (1-5 OPiv) were prepared and cross coupled with LiCuBu2, LiCu(CN)Bu, LiCuPh2, and LiCu(CN)Ph. Generally, coupling occurs at the least-substituted allylic system; mechanistic implications are discussed.

• Stereoselective Preparation of Dienyl Zirconocene Complexes via a Tandem Allylic C−H Bond Activation-Elimination Sequence

  zirconocene derivatives were easily prepared, as unique geometrical isomers, from simple non-conjugated unsaturated enol ethers with (1-butene)ZrCp2 complexes. This new methodology is based on a tandem allylic C-H bond activation-elimination sequence and the mechanism has been mapped out by deuterium labeling experiments. The stereochemical outcome of this process was determined by addition of several electrophiles

  从简单的非共轭不饱和烯醇醚与（1-丁烯）ZrCp2 配合物很容易制备出几种二烯基锆茂衍生物，作为独特的几何异构体。这种新方法基于串联的烯丙基 CH 键活化-消除序列，其机制已通过氘标记实验绘制出来。该过程的立体化学结果是通过添加几种亲电试剂来确定的。此外，当有机金属衍生物既是乙烯基又是烯丙基时，例如在 44-47Zr 中，在锆到铜的金属转移步骤中发现了意想不到的立体化学逆转。

• New Approach to the Stereoselective Synthesis of Metalated Dienes via an Isomerization−Elimination Sequence

  Treatment of Cp2ZrBu2 with enol ether containing a remote double bond lead to conjugated metalated diene as single isomer via a tandem isomerization-elimination sequence. 2-Arylsulfonyl 1,3-dienes can also be used as a source of dienyl zirconocene derivatives, and the stereochemistry of the diene is dependent on the transmetalation reaction.
