  Hydrogen-Bond-Activated Palladium-Catalyzed Allylic Alkylation via Allylic Alkyl Ethers: Challenging Leaving Groups

  摘要：

  C-O bond cleavage of allylic alkyl ether was realized in a Pd-catalyzed hydrogen-bond-activated allylic alkylation using only alcohol solvents. This procedure does not require any additives and proceeds with high regioselectivity. The applicability of this transformation to a variety of functionalized allylic ether substrates was also investigated. Furthermore, this methodology can be easily extended to the asymmetric synthesis of enantiopure products (99% ee).

• Copper-Catalyzed Dehydrogenative Cross-Coupling Reaction between Allylic CH Bonds and α-CH Bonds of Ketones or Aldehydes

  日期：2014.5.26

  A dehydrogenative cross‐coupling reaction between allylic CH bonds and the α‐CH bond of ketones or aldehydes was developed using Cu(OTf)2 as a catalyst and DDQ as an oxidant. This synthetic approach to γ,δ‐unsaturated ketones and aldehydes has the advantages of broad scope for both ketones and aldehydes as reactants, mild reaction conditions, good yields and atom economy. A plausible mechanism using

  以Cu（OTf）2为催化剂，DDQ为氧化剂，开发了烯丙基CH键与酮或醛的α- CH键之间的脱氢交叉偶联反应。这种合成γ，δ-不饱和酮和醛的方法具有以下优点：酮和醛均作为反应物，反应条件温和，收率高，原子经济。还提出了使用Cu（OTf）2作为路易斯酸催化剂的合理机理（DDQ = 2,3-二氯-5,6-二氰基-1,4-苯醌； Tf =三氟甲磺酸盐）。

  日期：——

  coupling reaction of allyl alcohols with trimethylsilyl enol ethers was performed by using a commercially available oxovanadium(V) catalyst, providing γ,δ-unsaturated carbonyl compounds in one-step. This catalytic system could be applied to a gram-scale catalytic synthesis of the γ,δ-unsaturated carbonyl compound and the deoxygenative coupling reaction of benzyl alcohols with trimethylsilyl enol ethers
