A practical copper-catalyzedhighlyregioselective 1,2-hydrocarboxylation of terminal 1,3-diene with carbon dioxide has been developed. Under mild reactionconditions, this chemistry afforded 2-benzyl-β,γ-unsaturated acid derivatives as products, which are a kind of important unit for bio-active molecules and versatile precursors for organic synthesis, with good functional group tolerance. The key

developed an efficient method for erythro-selective epoxidation of acyclic allyl-substituted alkenes, including allylic alcohols, amines, and esters. Up to 9:1 erythro selectivities for terminal allyllic alkenes could be achieved, which are significantly higher than that achieved using m-CPBA as an oxidant. In addition, the synthetic utilities of this epoxidation method were highlighted in stereoselective synthesis
通过使用[Mn(2,6-Cl 2 TPP)Cl](1)作为催化剂,Oxone / H 2 O 2作为氧化剂,我们开发了一种有效的方法,用于无环烯丙基取代的烯烃的赤型选择性环氧化,包括烯丙醇,胺和酯。末端烯丙基烯烃可达到9:1的赤型选择性,这明显高于使用m -CPBA作为氧化剂所达到的选择性。此外,这种环氧化方法的合成效用在关键的抗HIV药物中间体的立体选择性合成和糖基的环氧化中得到了强调。
