  Selectivities in reactions of organolithium reagents with aryl bromides which bear proton-donating groups

  摘要：

  Studies of substrates which offer an acidic hydrogen and an aryl bromide for reaction with an organolithium reagent have been carried out with a series of benzene bromo amides and bromo anilides as well as selected benzene bromo carboxylic acids, bromoanilines, and bromobenzylamines. A representative example is the reaction of N-ethyl-N-deutero-o-bromobenzamide (6-d) with 1-lithio-3-phenylpropane to give N-ethyl-o-deuterobenzamide (46%, 94%-d) (7-d), N-ethyl-o-bromobenzamide (6)(49%), 3-deutero-1-phenylpropane(51%, 92%-d), and 1-bromo-3-phenylpropane (48%). Product formation in this and related cases is explained by the operation of a two step sequence in which an initial deprotonation is followed by a bromine-lithium exchange which is accelerated with respect to mixing. Such a sequence is consistent with the results of deuterium labeling and with changes in product ratios on different mixing and with differently aggregated organolithium reagents. Support is provided for the operation of two pathways for the expedited bromine-lithium exchange reactions. In one pathway a high local concentration of the organolithium reagent promotes rapid reaction and in the second the exchange reaction occurs within an initially formed complex. The selectivity for removal of a bromine ortho to a lithiated carboxamide is found to be 5-8 with n-butyllithium, and satisfactory synthetic ortho selectivity is obtained for N-ethyl-2,5-dibromobenzamide with phenyllithium.

• Reaction of 1-arylpropenyl-lithium with t-alkyl bromides. The influence of substituent electronic effects and additives on the course of the reaction

  DOI：10.1039/c39860000242

  日期：——

  The reaction of 1-arylpropenyl-lithium (1a–c) with t-alkyl bromides proceeds by either a nucleophilic substitution or single electron transfer mechanism, the preferred pathway being a function of electronic substituent effects and the absence or presence of tetramethylethylenediamine or hexamethylphosphoramide.

• Enantioselective Inverse Electron Demand (3 + 2) Cycloaddition of Palladium-Oxyallyl Enabled by a Hydrogen-Bond-Donating Ligand

  Cycloaddition reactions between oxyallyl cations and alkenes are important transformations for the construction of ring systems. Although (4 + 3) cycloaddition reactions of oxyallyl cations are well-developed, (3 + 2) cycloadditions remain rare, and an asymmetric version has not yet been developed. Moreover, because oxyallyl cations are highly electrophilic, only electron-rich olefins can be used as

  氧烯丙基阳离子和烯烃之间的环加成反应是构建环系的重要转化。尽管氧烯丙基阳离子的 (4 + 3) 环加成反应很发达，但 (3 + 2) 环加成反应仍然很少，并且尚未开发出不对称版本。此外，由于氧烯丙基阳离子具有高度亲电性，因此只有富电子烯烃才能用作环加成伙伴。我们在此报告了一种钯-氧烯丙基物种与缺电子硝基烯烃之间的对映选择性 (3 + 2) 环加成反应的方法。这种转变是通过合理设计的氢键供体配体（FeUrPhos）实现的，并通过逆电子需求途径进行。使用这种方法，
