  钯催化对映体纯的α-取代的烯丙基硼酸酯的合成及其对醛的加成

  摘要：

  酒石酸衍生的硼酸酯2可以用SnCl 2进行钯催化的羰基烯丙基化，以获得对映体纯的α-取代的烯丙基硼酸酯8和9。该反应区域选择性地进行，并且具有高，简单的非对映选择性，从而形成反产物。将它们添加到醛中分别得到对映体富集的均烯丙基醇17和18。本文介绍了合成，表征和机械原理。

  Enantioselective synthesis of 4-substituted (E)-2-butene-1,4-diols and anti 1,2-diols are described. Highly diastereoselective reactions of aldehydes and the chiral PhMe2Si- and (C6H11O)Me2Si- substituted allylboronates 25 and 26 provide anti homoallylic 29 and 50, respectively.

  [GRAPHICS]We report the results of a combined experimental and theoretical study on the reaction of 3-bromopropenyl acetate in the presence of zinc with three different aldehydes (i.e., benzaldehyde, 2-methylpropanal, and cyclohexanecarboxaldehyde). A 80% de in favor of the anti product has been experimentally observed. with both saturated aldehydes, while for benzaldehyde, a 1:1 synlanti ratio has been found. DFT computations show the existence of three eta(1)-allylic organozinc complexes [gamma-(Z)-5a, gamma-(E)-5a, and alpha-5a], very close in energy. Only gamma-(Z)-5a and gamma-(E)-5a lead to the observed product. The computational investigation of the reaction of these allylic organozinc complexes with benzaldehyde and 2-methylpropanal demonstrates in both cases the existence of two competitive reaction paths leading to the syn and anti adducts, respectively. An anti preference has been found for 2-methylpropanal with both gamma-(Z)-5a and gamma-(E)-5a species (a diastereoselectivity larger than 80% is predicted), in agreement with the experiment. With benzaldehyde, while the reaction of gamma-(Z)-5a retains an anti-stereopreference (de = 70%), that involving gamma-(E)-5a is characterized by two degenerate transition states. In this case, the agreement between computations and experiments would be satisfactory under the assumption that the initial oxidative addition affords the gamma-(E)-5a zinc complex only. Additional MP2 computations have demonstrated that pi-stacking interactions can play a significant role in determining the relative energy of the transition states leading to the syn and anti products.
