  Regiocontrol and Stereoselectivity in Tungsten-Bipyridine Catalysed Allylic Alkylation

  摘要：

  Tungsten-bipyridine complexes, generated in situ, catalyse the allylic alkylation of isocinnamyl methyl carbonate by dimethyl sodiomalonate [NaCH(CO2CH3)(2)] with complete syn-stereoselectivity. When para substituted aryl-allyl methyl carbonates are employed, the regioselectivity correlates with Swain-Lupton parameters. Cross-over experiments demonstrate that the reactions do not procede via the conventional [M(0)] --> [M(II) allyl](+) --> [M(0) allyl-Nu] catalytic cycle.

  Co‐catalyzed allylic substitution reactions have received little attention, arguably because of the lack of any known advantage of Co catalysis over either Rh or Ir catalysis. Described here is a general and regioselective Co‐catalyzed allylic alkylation using an in situ catalyst activation by organophotoredox catalysis. This noble‐metal‐free catalytic system exhibits unprecedentedly high reactivities

  共催化的烯丙基取代反应很少受到关注，这可能是由于Co催化相对于Rh或Ir催化缺乏任何已知的优势。这里描述的是一般的和区域选择性的共催化烯丙基烷基化反应，使用有机光氧化还原催化原位催化剂活化。这种无贵金属的催化体系首次展示了与烯丙基砜的烯丙基化反应的前所未有的高反应活性和区域选择性，与相关的Rh和Ir催化反应相比，它代表了Co催化方法的独特合成效用。

  N-Heterocyclic carbenes (NHCs) were found to be suitable ligands in Ir-catalyzed intermolecular allylic alkylation reaction. In the presence of a catalyst derived from [Ir(dncot)Cl]2 (dncot = dinaphthocyclooctatetraene) and triazolium salt L7, the alkylation products from the reaction of aryl allyl carbonates with sodium dialkyl malonates could be obtained in 85–99% yields favoring the formation of

  bis-pyridylamides were prepared by microwave accelerated nucleophilic substitution of the 4-and 6-halo substituted derivatives of the parent ligand la. The ligands were used in the asymmetric allylation of cinnamyl carbonate catalysed by Mo(0) in which the 4-chloro- and 4-pyrrolidyl substituted ligand derivatives exhibited high regioselectivity (74:1 and 88:1. respectively) and enantioselectivity (96% ee), whereas
