• Development of general methods for the synthesis of new substituted allyl bromides as promising alkenylating agents
  作者：A. I. Moskalenko、V. I. Boev

  A general procedure has been developed for the synthesis of hitherto unknown substituted allyl bromides. The procedure includes preparation of the corresponding α,β-unsaturated carboxylic acid esters from accessible ketones according to the Horner-Emmons reaction, reduction of these esters with diisobutylaluminum hydride to allylic alcohols, and substitution of the hydroxy group by bromine by the action

  已经开发了用于合成迄今未知的取代的烯丙基溴的通用方法。该方法包括根据霍纳-埃蒙斯反应，从易得的酮中制备相应的α，β-不饱和羧酸酯，将其用氢化二异丁基铝还原为烯丙基醇，并通过PBr的作用将溴取代成羟基3。合成的不饱和化合物的E，Z异构体比例为3：1至4：1。

  γ-disubstituted and β,γ-disubstituted allylic alcohols were prepared and successfully hydrogenated using suitable N,P-based Ir complexes. High yields and excellent enantioselectivities were obtained for most of the substrates studied. This investigation also revealed the effect of the acidity of the N,P–Ir-complexes on the acid-sensitive allylic alcohols. DFT ΔpKa calculations were used to explain the effect of

  在这项研究中，制备了一系列的γ，γ-二取代和β，γ-二取代的烯丙醇，并使用合适的基于N，P的Ir配合物成功地进行了氢化。对于大多数研究的底物，均获得了高收率和出色的对映选择性。这项研究还揭示了N，P–Ir配合物的酸度对酸敏感性烯丙基醇的影响。DFTΔP ķ一个计算被用来解释上的相应的铱络合物的酸性的N，P配体的效果。反应的选择性模型用于准确预测氢化醇的绝对构型。

  Synthetic routes to α,α-disubstituted allylamines have been examined. Racemic compounds were conveniently prepared by thermal Overman rearrangements of primary allyl alcohols with trisubstituted double bonds, but rearrangement of these substrates by the only commercially available compound known to catalyze enantioselective Overman rearrangements, the cobalt oxazoline palladacycle (R)-COP-Cl, failed

  已经研究了 α,α-二取代烯丙胺的合成路线。外消旋化合物可通过具有三取代双键的伯烯丙醇的热 Overman 重排方便地制备，但通过已知可催化对映选择性 Overman 重排的唯一市售化合物，钴恶唑啉钯环 (R)-COP-Cl 对这些底物进行重排失败。相反，通过 CBS 介导的相应甲基酮还原获得的具有三取代双键的光学活性仲烯丙醇被合成并通过热 Overman 重排或烯丙酯到异氰酸酯重排转化为 α,α-二取代烯丙胺。两个反应序列都获得了高手性转移 (90-99%)，

  A number of permethrinic acid ethyl ester derivatives having various substituents [Et, Pr, Ph, Ph(CH2)n (n = 1, 2), etc.] in position 2 of the cyclopropane ring were synthesized, and their insecticidal acivity against typhoid flies., rice weevils, and bean aphides, as well as juvenoid activity on flour beetle chrysalises, was studied. The newly synthesized Compounds turned out to exhibit weak insecticidal activity against standard insects but pronounced juvenile hormone activity, which differentiates them from permethrinic acid esters.
