  The biomimetic construction of fused cyclic polyethers

  摘要：

  The formation of fused cyclic ethers by biomimetic synthesis was demonstrated. The one-pot successive ring-expansion reactions of bromo diepoxides were investigated by regarding the epoxy groups as the nucleophiles for the intramolecular cationic carbons to obtain the fused cyclic ethers.

  Catalytic Enantioselective Iodocyclization of γ-Hydroxy-cis-alkenes

  摘要：

  Enantioselective iodocyclization of gamma-hydroxy-cis-alkenes has been achieved using I2 in the presence of an unprecedented catalyst system generated from (R,R)-t-Bu-salen-Co(II) complex and NCS to produce 2-monosubstituted tetrahydrofurans up to 90% ee. While NCS turned out to be the essential additive, neither (R,R)-salen-Co(II) nor (R,R)-salen-Co(III) by itself is likely to be the active species responsible for the asymmetric intramolecular iodoetherification.

• Asymmetric Iodocyclization Catalyzed by Salen–CrIIICl: Its Synthetic Application to Swainsonine

  The previously developed enantioselective iodocyclization of gamma-hydroxy-cis-alkenes required 30 mol% of (R,R)-salen-Co(II) complex as chiral catalyst and 0.75 equivalent of N-chlorosuccinimide (NCS) as activator to produce 2-substituted tetrahydrofurans with 61 to 90% ee. Due to the considerable loading amount of the Co(II) complex, another more effective catalyst was pursued by screening (R,R)-salen-transition

  先前开发的γ-羟基-顺式烯烃的对映选择性碘环化需要30摩尔％的（R，R）-salen-Co（II）配合物作为手性催化剂和0.75当量的N-氯代琥珀酰亚胺（NCS）作为活化剂以生产2- ee为61至90％的取代四氢呋喃。由于Co（II）配合物的大量负载，通过筛选（R，R）-salen-过渡金属配合物寻求了另一种更有效的催化剂。当10摩尔％的催化剂应用0.5当量的NCS时，相应的Cr（III）Cl（84％ee），Mn（II）Cl（52％ee）和Co（II ）配合物（66％ee）。条件的完善建立了一种新的催化对映选择性碘环化方案，该方案使用碘在7摩尔％的被0活化的（R，R）-salen-Cr（III）Cl络合物存在下进行。
• Enantioselective Mercuriocyclization of γ-Hydroxy-<i>cis</i>-alkenes

  Asymmetric mercuriocyclization of gamma-hydroxy-(Z)-alkenes has been achieved using Hg(II) complexed with tartrate-derived 4-(2-naphthyl)bisoxazoline as chiral ligand to give rise to 2-monosubstituted tetrahydrofurans in 86-95% ee. Not only the linker connecting two oxazolines but also their 4-substituents were found crucial for high enantioselectivity. In addition, tuning the ketal protecting group of tartrate as well as adding MeOH and K(2)CO(3) worked beneficially.
