  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.

When the reaction is performed with a chiral enantiopure secondary acetate, the α-substituted cross-coupling product is obtained with complete inversion of the stereochemistry.

• Stereoselective synthesis of 1,4-dienes by chelation-controlled reduction of benzothiazole β-oxosulfides
  作者：Vincenzo Caló、Angelo Nacci

  日期：1998.5

  Allylated beta-oxosulfides of benzothiazole can replace beta-oxophosphane oxides to provide a stereospecific alkene synthesis. These sulfides, by reduction with sodium borohydride afford predominantly syn beta-hydroxy sulfides. DIBAL reduction in the presence of magnesium bromide improves the syn stereomer formation. Base treatment of these beta-hydroxy sulfides affords (Z)-allyl thiiranes which are converted into (E, Z)-dienes. (C) 1998 Elsevier Science Ltd. All rights reserved.
